Tough one...
In all honesty, if I'm doing something that would be dangerous/unacceptable for me to hypo (motorbike, exercising, dangerous tasks at work, etc) - then I'd run my BG higher than I'd usually like to. Instead of aiming for low 5's, I'd sit at 8 or 9. I achieve that by taking less insulin with meals, snacking or taking less basal in the morning.
The way I manage my diabetes is basically the opposite of what is advised. Lots of small corrections, micro-treating lows and advance bolusing. Although this is an effective means to manage T1, it does mean that hypos are more likely. Certainly I've found that to be the case.
I had a slight disagreement with my DSN about my BG's at my last visit. She was concerned at the amount of 4's and occasional 3.8 in my logs. I said that I still have all my hypo awareness (albeit I'm not a shaking sweaty mess and 4.0, but I know I'm not right). I am however, a sweaty shaking mess before I pass out from low BG, which is something I cannot afford to lose. It really boils down to what a hypo is defined as and also the situation you're in.
I'm currently walking the tightrope with a CGM and even then it's tough. Will all the fancy alarms and predictive algorithms in the world, there is still every chance of not catching a hypo.
I'd like to add that <3 hypos per week is possible if you're doing absolutely everything correctly. Throw some heavy exercise, a few nights out, couple of large meals and the general hectic nature of life... then I find 3 hypos in a week an EXTREMELY hard figure to get to.
For all of those out there who are almost always above 3 hypos per week, it happens
