I can feel the excitement there: ready to experience tea all anew. Best wishes for all the experimentations and trials and errors! They are part of the fun!
When your teapot is 260 ml, you have to accept the fact and work from a standard of 260/250 water to the equivalent amount of tealeaves. It’s okay. The teamug I use when I write holds over 260 ml. It’s not my contemplative teacup, but good for daily use and practical. I make lighter infusions and drink a lot of it.
Good luck!
