We have been using hc110 for over 30 years, ONLY AS A ONE SHOT DEVELOPER. the Fact that it was premixed and being re-used whould be a factor for me that to not use that batch. Everyone has their own "methods" but i would never suggest that combination of premix and reuse.

That combination of film and developer has been used quite often in our situtation with no problems.

Why not try it again using as a one shot developer and then decided for yourself?
