Help with pool size...

Ok, so I have been told by one pool guy that my pool is about 14,500 gallons. Another told me he thought it is around 18,000 gallons. But I just took some measurements and averaged everything and came up with 11,800 gallons. It is a free form pool, so that adds to the challenge. Below is a pic of the pool and my sketch with measurements (the x's are depth measurements). What do y'all think? I'm dealing with a pretty wide range here.

Easiest way to get a really good number is test FC with a recommended kit. Measure out 64 oz of bleach or somewhere around there. Add it with pump going. Retest FC in about 10 minutes and use pool math to see what pool size would give you the FC increase you saw from the 2 tests.

Hmm. With you getting almost 12k gallons, maybe 32 oz
