I don't understand the stand developing at 1+100 dilution. When I first heard of stand developing, the dilution was 1+200 for an hour. I've done it this way a couple of times with fine results.
For Acros, my standard developing is 1+100 for 18 minutes @68*F with extended agitation times towards the end. The only dilution and time I know by heart, everything else I have to look up.
