From what I gather from one of the best players here on WGT was that the extra distance number rating increase isn't so much when you're using any BS. (in a neutral wind condition)
Now, in GENERAL terms, let's say in a no wind condition for argument's sake, a ball with a 5.5 distance w/ back spin will have higher trajectory and land shorter then if no spin was applied.
But have tests been mapped that if a ball with less distance (e.g. 4.5) , in the same conditions and same BS, go longer or shorter than the 5.5?
BS and higher traj. w/ a high distance ball may mean you simply go higher and not all the time farther.
What I have heard is that the real extra distance rating from these balls may kick in when you add a little, or a lot more TS. (In general conditions)

[Yes, BS and a strong tailwind will give higher traj. and the wind may push is father because it's up there longer, and that's when you may get super long drives.]
[also, a frontwind and BS w/ a high distance ball may mean the ball gets pushed by the frontwind so it will not go as far, esp. w/ the added distance the ball goes higher and so, much shorter] AS SHOWN IN THE VIDEO*** A BALL W/ TOP SPIN GOES FARTHER IN A FRONTWIND than with back spin..
