I heard somewhere that you need to keep any category where it's at at 3-5 minutes--that 1 minute is basically wasting that minute.
Once a category has been maxed out, you can take all minutes out of it and it won't drop more than a fractional point. I use the 1 minute so that I don't have to dig through emails to figure out which red categories are maxed vs. which ones I just didn't bother to put minutes into that might still have a point or two of growth available that I can go after once cores are filled.
If a category isn't maxed, you need to have 7 minutes into it to hold it level, except for PER and LP, which hold level at 3.
