Sorry Daisy
I don't do technical and counting. I just work out what seems right for me on a
sensible suck it and see (literally!) basis.
I figure that's how it is for "normal" people and I don't want it to become the whole focus of my day.
BL will be back tomorrow, she's good at this stuff! Or ask your LLC, they'll probably know.
Good luck. You are doing great. I haven't had much time to post lately. My garden takes most of any spare time in the summer, but I often have a quick look on here before bed.
