Is there a current feature to include in the optimise calculation a loss of performance due to a sail change? 
Not a tack or gybing penalty BTW.

I'm running some cans race permutations, and I've noticed that I've a number of sail changes that only last 7 minutes and with a training crew I doubt very much that 7 minutes on an optimised sail will outweigh the potential for 'issues'.

Maybe someone has a workaround for this?

TIA
