90% KOH in Soapcalc

[cgsample]

I have the 2lb bottle of KOH from Essential Depot, but I don't know if it's 90% or not. Wondering if I should check the 90% KOH box in Soapcalc?

I'm looking at two different shaving soap recipes where one is checking the 90% and the other isn't. If my Essential Depot is not what I assumed, I may have made a huge mistake in one of the batches?

(tried to search forum, but kept getting "your search term is too short")

Thanks,

I use either Soapee.com where you can set the KOH:H2O ratio, or SBM that assumes a 3:1 ratio for my liquid soap. The paste is easier to work with.
