I don't have an exact idea about how, but I do think too that skirmish mechanics should change a bit.
I throw in a couple of ideas for the brain storming.
What if a successful escape to a skirmish attempt would raise the chance +0.01% for the next attempt? With a cap of, could be, 30%? 35%?
What if a technology would allow this +0.01% per tech level? Is it too much? It'd take one hundred successful escapes to pass from 20% to 21%. I don't think it is too much. If there were a tech like that, at level 20 it'd became a +0.2%, taking five skirmish escapes to pass from 20% to 21%. It seems easy, but it depends on how much this tech would cost and could be balanced with a high cost.
Or (totally different suggestion) what if the percentile of successful escape would depend on one of the total ATT point skill of the whole fleet? Or a combination of two? Could be Hammocks, maybe.
A fleet of five ships could have a max of 50 Hammocks ATT points. Lets say that this could be a +5% success (from 20% to 25%, with a cap in this case of 25%, not very much). A fleet of five ships with, for example, 40 total Hammocks ATT points would have a +4%. Etc.
If I had to vote I'd prefer the tech.
My two cents
