How long before my retirement visa renewal should I have 800K baht in the bank?

Keep in mind

, the seasoning is not counted from the date your current extension expires, it's counted from the date you apply for the new extension..

Those are two different dates; especially seeing as most offices allow you to apply for a new yearly extension 30 days before your current one expires (and some allow you to do it when you have 45 days or less left on your current extension)

The rules are clear, and in thai and english,

IF you are using banked money method for a yearly extension based on being over 50 (retirement) you need the 800K baht in the bank for 2 months before you apply for the extension (note that is not 2 months before your current extension expires)

Then you need to keep the balance at at least 800K baht for 3 months after you get the extension granted (some immigration offices give you a paper that has the date you come back to show the updated bank book balance to meet this requirement BUT some just look at the bank book and transaction history the following year when you apply for a new extension)

and then the balance can't go below 400K baht for the rest of the year.

So while I agree that different offices might tell you something other than this, believe me these are indeed the rules and if you stood fast and firm with a copy of them in your hand you'd get the extension.

I asked at Jomtien this week to confirm 2 or 3 months and was told 3 months.

When using the 800K baht banked money method for a yearly extension the money needs to be at 800K baht 2 months before you apply for your next extension, it needs to stay at 800K baht for 3 months after you got your extension granted, and then the balance can't go below 400K for the rest of the year. (7 months)
