LOL! While I was off hunting Marcy and Klinger's SS to post as an example of why it is good to start at 1u, she was actually here posting the same thing! LOL!
Anyway, I was going to post to take a look at Mars72 SS as a prime example of why starting Lev at 1u is a good idea.... here is her SS link or you could go through her sig in response above mine:

If you look back at her "NUMBERS" heading, that will show you she was up to 7u on Lantius, then her PZI was in the 4U to start I think- or thereabouts and it was really never very successful...when she started over at the 1u on Lev, no the numbers were not good, but in short order she is starting to see that the optimal dose is in the neighborhood of 2.75 to 3.0....if she had started at the 4u or more, she would have bounced all over, continuing those high reds until she finally decided to start over at 1u and then still had the climb at .5u intervals to find the 2.75ish that may work for her and Kilinger (knockwood,antijinx)
I can't access your SS for some reason, so I am taking a stab in the dark to assume the PZI isn't working for you guys, regardless of the dose....
It would be my suggestion also to start at the 1u, hold each dose for a MINIMUM of 6 cycles ( I prefer to hold 10-12 cycles) and then step up by .5u if you are in reds- be sure to check ketones along the way, of course....if you are getting some response, you may want to consider stepping up by .25u, but we can deal with that when the times comes.
Of course, we don't want your cat in the reds either, but no matter which way you look at it, there will be some settle time...You will likely have higher numbers anyway, and assuming you are having high numbers on PZI and that is the reason for your switch, what would it hurt to just start over at the begining and seek the optimal dose faster- from the bottom up, rather than top up, then down, then up again.
Unless the acro beans indicate otherwise, I agree with the 1u vote.
