Whilst this is true chemically, it's the delivery mechanism that causes the delay. The chemical composition of insulins like Novorapid (which my daughter uses) are slightly faster than regular human insulin, but not nearly enough to account for the aforementioned (up to) 30 minute lag.

Huh, thanks, I was not aware that novorapid is faster than endogenous insulin (most graphs show it much slower, albeit when taken subcutaneous). I switched from Novorapid to Fiasp because of how long Novo took to act, funnily enough.
Also, moderate-fun fact: intramuscular injections, while a bit painful apparently, can release insulin much faster than subcutaneous. By much faster I mean Lantus/24hr insulin can make you hypo within an hour, as per what I read online on a particular post.
I very occasionally do this with Novorapid into my shoulder muscle (one needs a longer than usual needle for this) to drop a high blood glucose fast, for example after a failed infusion site at night.
It does feel weird, but it does work.
