I have had 2 charging sessions with EA both on 350kW max plugs:
24.6 kWh in 18:31 from 27% to 57% for $12.56 (computed average charging speed 79.7 kw)

7.7 kWh in 7:27 from 50% to 59% for $5.69 (computed average charging speed 62.0 kw)

On the first session, the charger reported 99 kW at first. I couldn't believe it, so I took a picture. It quickly went down to around 80 kW where it stayed for most of that session slowly ramping down. It appears that the start SoC may have to be pretty low to get over 60 kW.

Bjrn Nyland has a graph that shows the I-Pace charging rate vs. SoC compared to other cars in this video from late September (WARNING: I-Pace isn't good, but the video has many interesting graphs and discussion):

I see in Ireland at least, Jaguar's website says it will charge up to 150KW. Is that new for 2020, or through a software update to earlier years?

That's a statement about the hardware. I doubt it changed for 2020 but could be wrong on that. I think they've had trouble with battery management software, so the hardware spec may be tough to meet unless they get more sophisticated with their software in the three areas that matter:
Discharge
Charge
Cell balancing

My totally speculative theory is that TSLA has that figured that out because they're a tech company ... JLR is still learning and probably doesn't have the same kind of team on it.

Well Tesla has changed these parameters in recent updates as they were prematurely aging batteries and also alleviating a minor fire hazard. My opinion is Tesla pushes the hardware too far for “performance” or bragging rights, and other manufacturers may use stricter margins and act more conservatively.

And Tesla has more data in units and time to draw from.
