Hi Sue.
With long term diabetics, some folk will use three drops under 50 (human meter). (that could translate as 3 drops under 68 AT)
Single drop under 40 (human meter) (no conversion for this as the comparisons run by many are not linear but the 58 Julie suggested seems sensible, not sure where you got the 54 for a reduction point from that seems awfully low for an AT)
Given that:
If Frankie dropped below 68 AT (but above 58) on three separate days that would give you a reduction.
But dropping below 58 AT on a single occasion would give you a reduction immediately
So looking as the ss,
Given that the 56 a couple of days ago should have earned him a reduction.
Counting back with this mornings 59 he has also had 3 drops below 68 also indicating a reduction is warranted.
What I am not sure about is if you should be using both methods together????
@julie & punkin (ga) could you offer some insight?
It get's quite tricky figuring this out for an AT since there is no reliable direct correlation between that and the human meters, and the protocol has been devised using human meters.

FWIW That's why I opted to use a human meter, even if it doesn't give you a reading that's comparable to a lab reading, in my mind it doesn't matter, what was important to me was following the potocol as closely as I could, and having the human meter made that easier.
