I am sorry no-one was around to help you. I see you gave 1 unit. Did you stall, not feed and retest to see if the BG was rising?.
I would also have tested after the +3 65 last night. With the AMPS of 86 this morning, I would think that Kitty dropped lower after +3 last night and most likely did 2 nights previously as well as you had a low AMPS the next morning.

No it shouldn’t affect anything except maybe stop her from dropping too low. It’s a good idea to have that out for her at night as cats often drop lower at night.She does have access to free feed on freeze fried chicken/beef at night but I don’t think that affects anything right?
it’s not an error. But put it in your back pocket for next time she drops lowI did not remember the rule to stall so that was my error
Very happy to help youthanks for your help
