That is odd. Maybe you got a lower than normal nadir yesterday and she bounced. The amps today is nice. I think skipping is fine.
She is doing fine. She just may be a kitty like Rumpel who is planning to do OTJ in her own way and on her own sweet schedule. You could look at giving U100 doses of .1 on the lower ranges and see if you can move the process along. Or just keep on doing what you are doing. She is in good ranges, under the renal threshold on tiny doses.
