So I have been doing more reading and I think my KOH base might be too low, getting conflicting #'s

The recipe I was following suggested 5.0 base + titration. The oil I am using titrates very low @ 2.0
25% methanol
This is a 4 gallon batch, with paint stir agitation processed for 60 minutes kept between 120-135F.

First batch I used 7.0/liter.

Second batch I used 8.0/liter.

So I have read more and find some other #'s for base using koh. I see 7.0 and 9.0/liter.

Looking for complete reaction, but not too much soap(read, easy wash)

Any advice appreciated.
