Yardage table for irons & cally's

  Jim I don't think there is anyone out there who takes these yardages as set in stone, this isn't an exact science we're analysing.

  They are a decent reference point to start with, you then call upon your own experience, course and hole to determine your own solution.

  Of course I wouldn't need to refer to Chris's if I had yours to look at instead.

  some sense at last.  thanks Tiffer, that's what YJ doesn't understand i think, and doesn't realise its just a rough base to work out your calculations for approaches because all holes will be different and you need to figure out yourself how to play them, just keep the table in your mind as a rough estimate on yardages from the balls

  i.e I know my 220 iron should give me "roughly" 235 yards with cally balls, some holes i might get 226, another i might get 239, but i take my calculations for wind presuming i will get 235 yards, but i know some holes will be long or short (i've played them so often), but if i use full back spin on the same iron it will "roughly" give me 217 yards most of the time, and from here i will work out my shot that's if if i need spin on ball for particular shot.  Its never going to be exact all the time, that's why i stressed "rough"

  And YJ what's it got to do with people "believing".  You think i just got those numbers randomly and made them up?  I got them by constantly playing the game, if i wanted to "fool" people i would have said my 120 yard PW was 148 yards with no spin and 100 yards with spin etc etc. Its for people like tiffer and others who want to roughly know how much extra yardages each club will give you with the callaways when your approaching the green.

  Invite me for a 9 holer sometime YJ and i can talk you through the shots i'm taking and you can see for yourself how it works for me.

  That was my first thought when I saw a consistent -4 drop across all your R11s with backspin. I went out to see if maybe I was the whacked out one with the numbers, not to prove you wrong. It was too much to ignore when I found what I did.

  Your entire whinefest since you've been here has always revolved around your clubs not doing what you expect.  Now it turns out they're just rough estimates. I'm with you on the not arguing thing-it appears your arguments are based on "rough" numbers now and I don't think you'll ever be happy with whatever clubs you swing. Knock yourself out-you are the champion and I shall remain your humble wannabe.

  This should have been your answer when I originally asked how you got them back on page 1. It was all I was asking. I am not interested in seeing how you do things, we are not in the same league. I would definitely be interested in seeing a MPC  with you against Bollox, Priestess, MrRenn, JakeStanfill or anybody else in their class. Maybe that Bollox Challenge would be something you should pursue.

  @Tiffer-you'd be lost-there isn't a chart in sight around here, just some empirical studies.

  Hitting up and down fairway is obviously going to give you different results, you need the slick tournament greens for the extra yardages to kick in

  Are you saying your stated yardages include roll-out on the greens?  Not just the club's carry?

  Yes Andy,

  I'm not jumping on one side or another, but the above has clarified many things for me in your past posts.

  Curious Chris, but do you play golf IRL?  Reason I ask is no one I know looks at any clubs yardage (maybe drivers) and factors in roll on the greens.  It's purely carry (as YJ tried) then assuming flat lie in the fairway, green slope and firmness.

  It's obvious your chart works for you, and now that I know how you have arrived at your yardages, I've got a better understanding.

  Anyway, break 60 in that RG!

  Exactly!  I believe that's what YJ was asking for but could never get a reply from Chris on how he derived his numbers. 

  Personally I base my shots on carry and then factor in roll-out based on green speeds, green slope, course, head wind, down wind, moon phase and club selection.

  LOL. Ty, Sir. Somebody gets it although you did forget to include your biorhythmic cycles. :-D

  Sorry but I don't see the confusion here? To me it's obvious that Chris is factoring the roll on the greens in coming to these yardages.

  Chris must be a player, who when 170 yards from the hole, considers playing his 7 iron (165 yards) with no spin or top spin, rather than his 6 iron (180 yards) with back spin @ 95% or whatever the percentage is.

  It is only by playing a variety of spin that he can determine the discrepancies in distance with the one club. Were he a player who puts backspin on all shots, he wouldn't even have considered posting this thread.

  I beg to differ. Were that the case the backspin numbers of mine would be greater than they are, landing on greens versus fairway.  Regardless, I understand how Chris is playing now because I do the same thing, just not as critically as he does.  I only use full or 1/2 so he's fine tuned it further and it obviously works for him.

   I do find it interesting that manipulating the spin as critically as he does yields predictable results. If I were a chart player I could also see how notes on top of his numbers to further define them could very well help someone.

  We're getting some where now Jim, other players input and how they factor their shots would be an added bonus, by looking at our different games and how we come up with the specific yardages is always a plus, like on one hole you get that particular yardage by playing one way, i might play it another, but by putting both our results out there people could experiment with the different ways, like i know my 135 iron will land on 132 yards or there about (burners) with full spin, but i havn't a clue where it lands (if this is what club carry means) with no spin before it rolls, i "expect" my 175 iron will roll to 185 yards, but i dont know what yardage the landing point will be before roll on green and without spin (maybe some one could give us their rough list). Yet 90% of the time if i give same club full spin it will be 172 ish yards & a bit less spin i can get it to 177 yards.  

  St andrews #11 is 180 yards, if i have left right wind, or right left wind, i will play this shot with my 175 iron (working out that it should be 185 yards with cally's) and hit shot with no spin and a touch under full power.  Gets it close most of the time, If i had say 10 mph headwind, i would use 190 iron with full back spin (presuming its 187 yards & wind)

  That's exactly what it means and all along I assumed you knew this. Carry is how far the ball stays in the air. My results all come from hitting the shot and then eyeballing the distance box while listening for the "thump" of the landing. It's always an exact number you can see. What happens after that is entirely up to where the ball lands but knowing this number is a huge help. Rollouts are too vague and susceptible to terrain that to try and chart them is an exercise in frustration.

  Having said that and knowing one's an apple and one's an orange, look at our differences in the back spin column and see how they compare to what you use. It could be useful to you.

  Chris, many thanks. The chart has been helpful to me already. I'm with you on the 'full backspin' aspect, particularly given that full backspin on the Burners can be overkill and definitely takes more off the distance than would, for example, full backspin on the G10's. But wouldn't I be right to assume some backspin for the benchmark figure - for example halfway down? I say that just because some backspin on approach shots to fast greens seems to me to be 'best practice' to keep control of the shot.
