Coinbase API USD balance is off (rounding precision)

I noticed yellow warning for Coinbase awhile back and every time I would look at its balance would increase very small amounts. It’s obvious it was my advance trades… they were off by just one cent. It was bothering me so i manually imported all my trades to try match what was reported. Got it to 0.0059208 calculated out of 0.00 being reported. I guess I can just ignore it at this point. Anyway along the way I found outlier of 9 cents:

Also 4 out of 6 coins in the last two weeks of November were not even imported. USDC advance trades sync perfectly.
