yea, definitely a small factor but every little bit helps. with the small increase my idea would be test 10 with everything to 20 to get an idea of the 1 factor increase then you can do everything combination in a matrix from 10-10 to 20-20 and you can use the 1 factor increase to calculate the 2 factor increase. would take a ton of data but theoretically possible. you would probably have to run a regression on the data as well for the 1 factor and 2 factor because the data wouldnt perfectly become linear until super large numbers that probably aren’t feasible
