I know I'm being a dog with a bone here and your science is of course good but I just noticed another anomaly.

Leg two that starts at the bottom of the page and goes about NE is amazingly fast. I checked the track details and from 3:51 which is about the start of the turn to 4:11 which puts "8A" abreast the log show speeds of 6,7 and 8 knots. I'm pretty sure I had only the jib up reefed to 100 percent so the only other explanation I can figure is that the current is wicked fast right there like maybe 4 knots, more than double what is predicted.
The other anomaly is that I remember not being able to head up any more than my 50 degrees.
That particular leg really bugs me.
Given the conditions I thought I had I would have predicted a course of about 10 degrees.
What I got was 50 degrees and super fast.
I expect my predictions to be off 5 10 degrees. I'm not good enough at ascertaining the actual conditions to be more accurate than that and in this case I know they changed too.
But to be off 40 degrees hurts. And 8 knots, I was moving but it did not seem that fast.
