I figured a slightly higher rate but less than 80 kW average.
The Bolt EV’s average charging rate from 0-62% is probably just above 50 kW (51-52 kW?) on the new generation of CCS hardware. What really matters to drivers, however, is miles added.
The I-Pace has a roughly 50% bigger battery (90 kWh vs 60 kWh) but around the same 240 mile range as the Bolt EV so it would have to average a charge power 50% higher to add the same number of miles during the same charge time period.
So, I figure it was maybe charging just somewhat faster (10-12% faster?) than a Bolt EV in miles added per charging time in that apparent 40 minutes.
However.... the charging time we saw — 62% in just under 40 minutes — does not match the claimed 80% in 45 minutes. Something is not consistent there. Perhaps they didn’t begin charging at the very beginning of the video or perhaps the charging conditions were a little wonky with the car being under the TV lights and the battery cooling system detuned in order to not be making too much noise. The implied charging rate at the 8 minute point, however, did seem closer to 95-100 kW. I dunno.
I skimmed back at your posting history and it looks like you ordered your Model X sometime in late spring or early summer and received it by August of 2016. Just 6 months or so earlier at the beginning of 2016, the Supercharger network looked like this:

The first I-Pace deliveries will begin in the “2nd half of 2018” but many folks will probably get theirs in the first half of 2019. If you believe Electrify America’s latest statements on their website, their 150+ kW charging network will look like this by June 2019:

That represents about a year’s worth of relative charger installation advantage for Tesla. And, of course, plenty of folks here happily bought their Model S back in 2015 in anticipation of that Supercharger map above.
I don’t think a lack of US ultra-fast DC charging will be a large barrier to potential I-Pace customers who are drawn to the car for other reasons.
No doubt, today’s (or 2019’s) Tesla Supercharger map is much better than what Jaguar owners would get from Electrify America’s June, 2019 highway network. I suspect that EA’s map plus metro DC charging from EA and other providers is “good enough” for many potential buyers given the assumption that charging infrastructure will continue to get better while they own the car.
