Now for something fundamental: I've been traveling to Thailand for 50 years (150), formerly for business, now for pleasure. I've never overstayed my visa. I have to say that many guidebooks give incorrect information. The 60+30+7 entry rule refers to land entry (visa hopping), which will soon be a thing of the past. Because of my travel class, I can use priority processing at immigration, so nobody has to worry about me, and I also speak Thai, which is a plus in Thailand. I was very pleased with the various comments, thank you very much.
