Thing is with these numbers, you aren't going to see many people reach the 50 TPE threshold in that case. Assuming an 8 season career and current carryover percentages, you'd need 715 TPE to beat the threshold. That's a little high for me. Given that 400 TPE is the threshold for Welfare, that seems like a reasonable number to beat... which consequently, is just about 30 carryover (400 x 7% = 28).
And speaking generally, the 75 TPE threshold, you need 1085 TPE to beat that, so what we're discussing here affects probably 5% of high-earning members that are probably recreating no matter what anyway. Just something to keep in mind (don't really care myself, I'm more in line with Victor's "if it ain't broke" mantra)
