Sorry mate - I confused your 4000 rounds with the count of 400 for Legends.
Ty, oily, to correct my error.
Ihatecheats:
Thank you alosso, even though some of that went over my head. My best round 18 is 60 so I don't think I will be shooting much better rounds than that and a 27 for 9 holes is on my limit.

Is my estimation of 70 rounds of 7 under per round enough to get me under 60 average from where I am now?
From oily's calculation, you must get rid of 277 shots compared to the avg of 60.69.
The term "7 under" is not precise here because the absolute no. of strokes counts.
I assume that you're talking of 36 - 7 = 29 strokes for nine hole rounds(?) = 58 for 18. (at RSG and OAK -6's would do it)
70 rounds of those better your average by 70 x 2.69 = 188 strokes - not enough. 103 rounds of 29 would do it (103 x 2.69 = 277,07).
Any other round of 60 and better (e.g. 59 on 18 holes) will bring you closer, too.
Even if you'd shoot nothing better than 60 you'd achieve your goal, too.
And, since there will be a few higher rounds in the calculation now, also a few 61's and higher will add to it by kicking out these higher scores.
