I think that many, if not most diabetes docs are overrun with folks who are not "managing" their BGs well, so someone who shows up with a consistent range of 85 - 125 as an anomaly. Similarly, low A1Cs are seen with the suspicion that they have been achieved with too many low BG excursions and the frequent recommendation is to have a bit higher A1C to prevent excessive lows.
On my diet (aka, NOT low carb!), a BG of 125 two hours post-prandial would surely lead to a low @ 4 hours post. I would also not be terribly concerned if I were to hit 180 if I returned to my pre-meal BG by 4-5 hours post. This is especially true if I started out a bit higher pre-meal, OR if I were hitting 180(+) after every single meal. Conversely, If I ran to 180 or higher and stayed there for hours on end, I would definitely correct.
One thing my CGM has consistently shown me is to not pay too much attention to my 2-hr PP. I frequently find the most significant drop comes well after 3 hours PP. YDMV.
