I would all in maybe 5 days, and then I would take some time away and get a fresh perspective for a couple days. If I come back and and still like it, then I would probably just do some minor tweaks and be done.
Worst case is I have to do fresh mixes in 3 days instead of the original 5.
Day 11 would be to pick the best out of the 2 or just leave the country.
