I already explained this to you. Do not use the 100 and 200 BECAUSE IT SAYS DO NOT USE THE 100 and 200.
"These" caculators? My calculator is unique. Other calculators do not use 2 inputs and that is where they lose accuracy. It does not make sense to compare my calculator to 1-input calculators.
This calculator DOES give good results for ALL athletes. If 2 athletes have the same ability at 2 distances, then they will have the same ability at all other distances. I do not understand why you think 2 inputs is not enough. 2 inputs is all that is necessary.
When the calculator does not produce good results, it has always been because of the user (you).
1) not following the instructions to not use 100/200 times
2) not using the optimizer BEFORE using the calculator
3) not making sure the PBs were achieved in the same period
You failed at ALL THREE of these mistakes. This is why you are getting wrong numbers. The calculator is not the problem. Your use is the problem.
I am open to the possibility that my calculator is flawed, but in every case so far, it has been user error.
