Kia/eGMP Charging Speeds at Tesla Superchargers Wrong?

I was trying to compare taking our Kia EV9 versus F150 Lightning for an uncoming 1000 mile trip (from SoCal to Boise via Utah) when I discovered that the charging time ABRP shows for Kia assumes that the Kia is getting 250 kw from Tesla when we are limited to 95 or so.

When I went into each stop and manually configured it from 250 kw to 95 kw till x percentage (as determined by ABRP in the first place), the charging time went from 3h 19m to 3h 57m. (The Ford preferring Tesla for comparison sake was 3h 36m. At first glance, it seemed slower in the Ford, but after fixing the Kia speed, the Ford appears to be faster.)

It's not a huge difference in the sheme of things and I hate to admit it, but one probably saves more time at Tesla than it costs in going to a full EA and then going to Tesla anyway (as happened to me on my last trip from NorCal to SoCal.

But I'm confused, because it does factor in something for going to Tesla, because when I don't prefer Tesla the charging time is only 2h 26m. Is this fully because it assumes 350 kw at EA and 250 kw at Tesla across some charging curve? (This is a full hour less than Ford at 3h 27m, but depends on a number of EA stations being open/available.)

It also makes me wonder if/how ABRP takes into account the charging curve of the vehicle when calculating charging time too. I think it is smarter than taking 250kw or whatever a station is capable of and putting that into the battery size. Assuming that's the case, it shouldn't be too hard to add a limit for eGMP vehicles at Tesla stations to 90/95/100 kw.

I ran through some more scenarios and it seems like ABRP defaults to 120 kw for the Tesla stations. I got roughly the same 3h 19m result when I set each to a manual 120. This is obviously less than we would see at even a 150 EA (which is more like 170) and not the 220 or so the EV9 would see on an ideal station. (I get there is a curve, so the max speed isn’t maintained for the entire time.)

So it seems that ABRP knows we aren’t going to get the max, but why 120 kw instead of 90 or something more reasonable?
