How do we decide if it is still safe to let him go without honey?
You need to assess, where the numbers are coming from and where they are probably heading.
You did a good job of that last night.
that 20pt drop into the 70's in 30min, at +3 so still early in the cycle (looks like he onset a little before +2), probably required some intervention to help him flatten out, the two drops of honey seemed to stall him though, he wasn't clearing a bounce, so possibly a little less honey or just LC at that point might have done the trick. The two drops worked better than the morning amount, but maybe still a bit too much.
So if he is having a more regular cycle (not a bounce clearing) next time you could try either one drop in his food or LC. Either would be safe, you have the tools, experience to manage his numbers if he drops below 50, remember 50 does not mean he is hypo.
Really you want to reserve HC/honey for when he drops below 50.
In a situation like yesterday, you might have used higher LC or MC at most to slow him down. (if you were using commercial food that you knew the carb content of)
So I would say don't use anymore than a drop of honey added to your 10g of HM (let's call that MC, though we don't know if it is), the problem with intervening too much with honey is that the depot can become overfull and you end up masking the need for a reduction and when he does finally insist on the reduction you can end up with him making a big point about it and having to intervene quite aggressively to stop him from going to low, I had that happen (well below 50)
I would reserve using any more than a drop for when he drops below 50.
The managing the curve with food, helps you hold on to the dose, flatten him out and can help with the bouncing as it sees him spend more time in green/blue numbers.
You need to also recognize when he is having a bounce clearing cycle, with those he might need a bigger nudge to make him take notice.
