gave her a few crunchies or food
If by crunchies you mean regular dry food, this is not the best idea.
When using food to manipulate the curve, as you are doing TR you should not be using dry food at all. You should be using wet food, of varying carb content.
If you found yourself in an emergency (she was well below 50, and not coming up and won't eat anything) then you could use dry, it is in the hypo kit. But other than that it is a prerequisite of TR that no dry food is used.
Dry food can stay in their system longer and can really inflate those numbers, increasing her insulin requirement.
For example you fed 8 crunchies on March 7th at pm +8.75 when she was in low yellow, to bring her numbers up, that wasn't necessary, with Lantus apart from having her spend most of her time in green you want to be aiming to shoot progressively lower numbers, ideally you want to be shooting green. On march 7th after those 8 crunchies she climbed and climbed and hit black, the dry food you gave could well be responsible for that.
I know from experience with my George that when he accidentally got into kibble, it took about 8 hours to see his numbers rise like crazy and about 24 to 36hours to see his BG return to normal. This can of course vary from cat to cat.
In any case using HC kibble will make her numbers look worse on any dose.
Is she a recent wet food convert, it seems from your notes on the SS that you are struggling to get her eat?
I sprinkle freeze dried treats (zero carbs) on the top of LC food when when one of my cats is being fussy about eating his fuds, perhaps you could try that.
