Approach R10 Driver distances... Still terrible unless you swing at 125 mph+. Alternate apps?

I have seen all the complaints about how bad the r10 is with driver stats. Interesting observation... I am broken and I am down to 90-95 mph swing speed. Driver distances for me are way off as compared to my ES14. Launch angle is usually out to lunch. Up to 40yrds short distance wise. However, my 2 elite golfer sons who have a fairway finder swing speed of 120 mph have their distances showing up pretty close to their trackman sessions with their coach. 

Algorithm for figuring out carry distance must favor speed.

I have heard there is an alternate app that works with the R10... Awesome golf... Anyone use that instead for range work? Any better with driver stats?

Thx.
