Good drivetrain calculator

Any good drivetrain speeds calculator, that also gives you acceleration details?

Here’s a fairly recent JVN calculator. Paper: JVN's Mechanical Design Calculator 2016

If this does not cover your needs, please amplify what you mean by “acceleration details”.

If you want a very in-depth simulation including acceleration, electrical load modeling, etc. I recommend this one:
Paper: ILITE Drive Train Simulator, v2019

whats the diffrent between time to goal and total time?

My design spreadsheet has a sprint distance calculator that estimates drivetrain acceleration based on Ether’s model. It also has a number of other useful calculators and features.
