First you would need research demonstrating that the ideal training regimen had been discovered. Then that regimen would have to be applied to test groups to determine various individuals' "genetic potential", and determine predictors of an individual's potential. Then you could know whether your gains had stopped because that's all that you could reasonably expect. That's the ideal, but even some indication of potential given use of good training practices would be interesting. Unfortunately I suspect that individual variation is such that we may never get a good enough predictor of such things to be very useful.
