Yes, BTS/MRT is nice system. But have you been to TPE, SIN, Tokyo and other major Asian cities? Their transit systems much more advanced. BKK late to the game.
Good luck Vinci. Let us know if it is successful. Lots of people in that same status.
Rogue Immigration agents can put the proper stamps in your passport to look legitimate. But I really doubt they can go in immigration database and backdate data. Any good database system does not allow backdating and also tracks person making the entries. Anyone IMO trying to do that is easily busted.
Vinci shows up with appropriate stamps in passport but immigration database recognizes the fake entries. Busted big time. Just my IMHO.
I had the same situation last year. On paperwork ask for 180 day extension and write a short note that you want to extend for 180 days, not 365 days. Worked fine for me at Chang Wattana.
Wait time for notary service in Bangkok can be a very long time - weeks. I ended going to Vientiene for embassy notary services. Much shorter wait time. Plan ahead!
Whether a physics or engineering issue, conservation of mass and energy still apply which is what my basis is. Also elimates need to try to estimate HT film coefficients and blackbody radiation.
