___If you can do without assist under most circumstances and use good thermal management, you might never have one. I don’t know your local NH. terrain but if it is mountainous, you are probably forced to use Assist more then some of us Midwesterner’s unfortunately. The good thing is that if you do live in NH., your summer time temps are more then likely lower then those living in the south and southwest. In any case, on the warmest days, get those windows cracked while parked in the sun. Trust me, it works really really well.
___I have a minimal pack use driving style and always use good thermal management. With that, I have never had a recal at the 64,500 miles mark and actually don’t ever expect one.

I oversimplified my reply a bit. A CVT has an additional dimension of battery SoC control in that it can "downshift" the CVT in balance with the IMA's SoC to better manage overall IMA battery performance.
I've read several reports over the years from CVT owners that the do not experience the "traditional" dreaded recal. Specifically the loss of power during the event.
Although I have corresponded with one CVT owner that correctly pointed out that he had seen the SoC rapidly fall without a sustained assist to explain the event.
Given this better ability to manage the battery by balancing ICE with IMA power overall recals are _reportedly_ less frequent with CVT's than 5 spds.
My theory is that the CVT models normally run in the 2500 rpm range. Only a CVT driver can verify this. (We need some stats on rpm vs mph in a CVT) Also they apparently put a different BCM into the CVT's. (Different part number.)
After My original IMA battery was replaced, (a new BCM came with it). I saw a different "pattern" of IMA charging versus the old one.
If you keep a constant 4 bars of assist during a slight uphill climb, once the IMA gauge gets to the horizontal position (1/2 full, or empty), the assist will stop and 4 bars of regen will start. Keeping the same throttle position will slow the vehicle gradually because of the regen and the battery will charge back to "near full".
What do you think?
Maybe that is why Honda selected 2500 rpm as the "sweet spot".
