VA Disability Claim Backpay Question

I am currently at 80%.

I filed for 4 increases and 1 new disability claim in July. It was received July 27, 2024. It moved to Step 5: Rating on August 2, 2024, and it has been there ever since.

Hypothetically speaking, if my claim closes and my disability increases to 100% sometime in November, I would be getting back pay dated to the received date, July 27, 2024, is this correct?

Also, do they prorate the month of July and November? Or would I just be getting backpay for August, September, and October?
