25 days seems like a really good number to go with. If DMC meets on, or around, the 28th of October then we could expect an update around November 23rd (which is a Monday).
If I assume the FDA wants this data before issuing an EUA then we could potentially see it around the 1st week of December.
That would also be in-line with Dr Javitt's chart of distributing IV in 2021.
