If they have the same temp & dev times shouldn't be an issue. Agreed. Also b/w development isn't an exact science. Some variations in temperature or development times are totally acceptable.
Yes but the key is it be consistent. If it's a flat day and the entire roll was shot on in the same light if you increase your dev time you can increase contrast. Just the opposite for to much contrast. Decrease dev times. The key is to first figure what the normal dev time, temp and agitation is and work from that.
It becomes an exact science if you do the zone system correctly but it is not real practical for roll film.
