From a purely hypothetical standpoint, do you guys think that one section of full page of blotter absorbs a higher concentration of LSD than another section while being laid? For instance do you think that the center picks up more or do the corners suck up more? I've wondered...
Not likely. When your tabs are soaked and no solution remains pooled on top, the soakédness ensures that all of your LSD/drug is distributed evenly. Each tab should hold around the same amount of liquid at this moment.
Just make sure the tabs don't "warp", which may cause solution to concentrate at the center of the sheet.
