I honestly didn't even think about it lol (although I did think that it would be more logical not to double 16x16, but to reduce 48x48 by 1.5 times)
You can reduce 48x48 by 1/3 too yeah. But it doesn't always work out that well. I get the best results by using 33.33333334% That has gotten me the best results so far at least.
