With my T, I think it varies by day. I know that on Mon, Tues, and Thurs, she works 9 to 3 and on Weds she works 9 to either 6 or 7. I know that she usually has an hour break around lunch time, but will sometimes schedule appointments during that time.

So, 4 or 5 clients on Mon, Tues, Thurs, and maybe up to 8 clients on Weds.

She has enough workload that it's difficult to book times with her outside of my standing appointment, unless I do it several weeks in advance.
