There's not a "right" answer here. I wanted you to be clear with respect to your options given the parameters of the protocol. Boo Radley already has a shed and there was no reason to hold the dose for 10 cycles. Some beans prefer to be more aggressive, others -- not so much. Then, of course, there are those pesky life issues like your schedule, what's easier to measure, etc. I've certainly held a dose for an extra day because the weekend was coming up and I would be able to monitor more closely.
If you want to split the difference, increase tomorrow PM -- that will be after 5 cycles. If it will work better for your schedule to increase on Sunday, that's absolutely fine.
