Of course these calculators will be for entertainment purposes only, (much like the rest of this site?) They are meant to be provocative not necessarily indicative.

I've got a bunch of quantitative models I've worked out over the years that I'll put up here. Here's one:

• Optimal Race Weight

Others to come:

• Swim vs. Run Ability
• "Are You a True Amateur?"
• Performance Pies
• Race Value Calculator
• Determining your Percentile.
• ..and more!
