It will never do that. Not even close. It has never stayed above 100 Kw for long. I have not timed it.
It should last longer than 10 seconds though if you started out above 100 Kw.
It goes down quick because your adding at rate of over 500 mph.
You will never see over 100 Kw if SOC is over 50%
Most everything you've said follows the chart that was posted. You'll not on the Red line, but not that far off.
I don't have a lot of warm weather experience but if it sees the pack is to warm it will not charge fast either.
Just because it's 75F doesn't mean what your battery is at. You could have been pushing hard and battery is warm.
Or it was a cold night and warmed up fast, but the battery is not warm yet.
You'd really have to state a lot more parameters to judge if your battery has and issue.
But with what you have shown it's all feasible for "normal" behavior.
We'd all love to see 115 Kw for 40-50%. But that would be double what Tesla claims.
115 Kw is over 500 mph. 50% of a 310 mile range battery is 155 miles.
That would be 155 miles in 18 minutes. Sorry pal, that's not gonna happen.
Well, what can we say except that you're completely wrong.

My charge here shows I'm at maximum charge rate (~115 kW) for more than 10 minutes, and above 100 kW for nearly 13 minutes.
I was still at maximum charge rate (115 kW) when the battery state of charge was crossed 50%.
I didn't get down to the stable value that the OP says is his "normal" charge rate of 74 kW until I was at 67% battery charge.
Oh right ... that was in the summer where it was 95F outside. Want to look at another one? Same vehicle, on 12/7/2018:

This time it's 48F outside. Same charge curve. 115kW for 12 minutes, over 100kW for 15 minutes, crossed 100kW at 50% SOC. 74kW at 63% SOC.
Dude, you can't sit there and claim "oh it'll never happen pal" when I have concrete evidence to the contrary.
