B = 1 + (SD-1)*exp(-P/35)
might even be more severe than the currently used system. Zenhussy's block is an extreme case having large P and D; it should not be used as a representative example. Moreover, the values for r (r = 35 or r = 39 depending on which type of exponential function is used) were suggested by me based on the formula
B = S + D*exp(-P/r).
If you're going to use a different formula, then the values for r should be recalculated.
But it's your website, so do what you want / must. Just remember, this might be cyberspace, but there are real people involved who's lives are being messed around with.
