Livvy's Lady

This is scary stuff for me, so I'm starting a new thread, migrating from http://www.felinediabetes.com/FDMB/...ad-first-experience.177971/#post-1964664...in case it helps others, too.
So as posted on the other thread, I took Livvy and our new Alpha Trak II to the vet today. The tech took a vial of blood and tested a drop of it with the vet's glucometer and another drop of it with our glucometer.
Ours read at 188, and theirs read at 145.
This was at about +9.5.
Two things have my head spinning:
1.) Those are some really different results...and based on a small experiment that I did (testing two drops of blood five minute apart with the Alpha Trak resulted in readings 26 points apart), I'm wondering how different they "really" are (over time, upon repeated measures). How do I feel confident interpreting these? The vet said that his meter is comparable to our in terms of giving cat-specific readings. But what if our meter happened to read low that time, but on average isn't that different than ours? Would the adjustments that we make be biased/incorrect/dangerous? More specifically...
2) The vet looked at his reading and at ours and gave the following guidance. Please recall that Livvy is on 3u/dose. If her PS reading on our Alpha Trak is:
- between 101 and 150, give 1.5u
- between 71 and 100, no insulin
- 70 or lower, be concerned, give her Karo plus some food, and if she perks up, great, but contact him. If she doesn't perk up, get her emergency care.
Please recall that these guidelines are specific to what he has interpreted as the scale that our meter is on - a biased scale that tests higher than reality. But the differences between our meters was 43 points!!! 43!
Do these guidelines seem reasonable given the context?
I feel very confused. I guess that the clinical signs must be more important than readings, because readings seem to be very imprecise.
Any perspective that you can offer will be appreciated for sure.
