Thinking out loud - improved speed calculations

DMW · 06-11-20, 05:02 AM

Note: I just repeated the speed experiment and got pretty much 0 error, my bearing wasn't on 11.3° so maybe this isnt such an issue as I thought

I was going to repeat because using % as an error before non-linear equations isn't really fair.

I also did a quick test in the tutorial

Speed measured using map = 6.08 knots
Speed calculation with 1 boat length = 6.17 knots, error 0.09
Speed calculation with 2 boat lengths and rounding = 6.014 knots, error 0.066

Maybe no significant gains here either!
