I think this is largely going to depend on what you are comfortable with and whether you are able to monitor today. I have limited experience with ProZinc but if Ember were mine and I could monitor, I'd probably give a reduced dose to try to keep her pre-shot numbers down. I'd wouldn't want to skip totally and lose the ground you've gained. You shot a 178 with 2u the other day and Ember had a beautiful blue cycle but still had some room to come down so I think a reduced dose of 1.5u or even 1u if you are more comfortable with that, should be fine as long as you can monitor today.
