I think that that is not necessarily the case RPC.
Look, if you use your working solution 'one shot', there is a built-in consistency there. The TIME and TEMP needed will be consistent for each film because EACH FILM gets its 'new' developer.
Any necessary restrainer has already been added to the developer by the manufacturer. I have NO problems with fresh film yielding absolutely NO FOG and I use NO starter with my 1+14 dilution (see my recent 'dilution' thread). In fact, the film I normally use 'expired' in 1998 and kept cold: Fuji Super G+ 100. - David Lyga
