  Not sure if this is the right answer, but it could be because the reverse view will not always be 180 degrees from the front view, it could be 160 or 200 degrees.

  Yeah, I was just going to say its hard to find the same dot in both views because the front view is so skewed from the cup.  I should have chosen a better spot.

   

  IDK if a 20 degree +/- opposite view would make such a difference 14 feet away. It's almost twice as slow in reverse. I wonder if the distance the camera is away from the pin in each view would make a difference.

  This is particularly curious to me because I do most of my putting aiming in reverse view. If I'm not seeing the true speed of the dots that could explain a few things.

  Same here, and have you ever watched a putt that when you look at it in reverse view it might roll over the hole but when you watch it in front view the putt seems to miss left/right of hole and not over it like in reverse view.

  To be comparable a dot has to roll over the same area of the green.  I tried to find a dot that is comparable in the front and reverse view.  The closest I came is the dot halfway to the pin on both views.  A line from the ball to the cup crosses close to the center of the dot's path in both views.  I say close, middle of the path in front view,

  

  25% of the path in rear view.

  

  I'll call it "Dot D".  I measured the time it took Dot D in Movie Maker. 

  In the rear view it took Dot D 16 seconds to make the trip.

  In the front view Dot D barely moves at all.

  Since the speed of any dot is constant across its 2 foot path, the dot speed IMO is representing the average slope of that 2 foot path.  Being just 25% off the center of that grid could I imagine account for the difference.

  Definitely would use chip view on this putt.

  I'm making a concerted effort to aim from the front view and then just see what that aim looks like in reverse. That speed difference has me concerned as I can't see a valid reason for it being as different as it is. I see what I consider an inordinate number of my  dinged putts just missing and now I'm wondering if it's because I trust the reverse view too much.

  Side question-what do you think making those squares 1 foot instead of 2 would do? I'd like to think it would be easier to see the green contours.

  Yep, would give more detail and a bettter read but I also think it'll never happen.  It would require twice as many dots and lines and increase CPU/GPU usage by probably 2x as well.

  I also use reverse view to actually move the aim marker, I find I can move it more accurately and get it just where I want it.

  I think there's also a psychological benefit in seeing the hole so close up and big though, it looks harder to miss in reverse view.  I always actually make the putt in forward view but seeing a nice big hole to aim for does give a touch of confidence.

  So long as the break is being shown correctly that is..........
