What are the consequences of not meeting Thailand's financial requirements for a non-immigrant O visa extension?

Maybe a anticipatory question and nobody wants to take the risk, but anyone already knows what happens when you do not meet the 'secondary demands' of the financials ?

(year extension after non imm o single entry based on retirement over 50)

1. If an immigration office checks the balance after 3 months of 800k at the 90 day notification and it dropped below a bit but at 'checkdate' it's 800k again ?

(or not)

2. If an immigration office checks the 3 months 800k and 'no drop below 400k' only next year but when asking new extension the 800k is there 2 months before ?

Sorry, a rhetorical and perhaps far-fetched question, but would you get a fine ? Maybe a refusal of next extension whatever correct financials you then want to use ? Especialy with my point 2 example, I would almost say you got an illigal extension of stay of 1 whole year !
