How does the 90-day reporting requirement work for multiple entry retirement visa holders in Thailand?

So I have now got my retirement visa and a multiple entry stamp valid until Jan 26, 2026. I went back to the UK Dec 28 (before my 1st 90 day reporting was due) and I asked the Thai lady at the bio passport check did I need to get the passport stamped instead of using the bio system to show I was leaving. She said no it is now all recorded electronically. My question is if left before my 1st 90 days was completed and I'm due back in Feb 28 does the clock start ticking again from that date for next 90 days... correct or not? and if so and I intend to visit UK before the 90 day limit each time do I need to report to immigration at all, also if I go for a holiday to a neighbouring country and use the biometric passport check at the boarder each time will I be ok🤷
