Horrible lines but their car seems to be running a lot more power, going at least 10mph quicker (120mph+) into the last turn, plus they're running soft tyres.
More power would mean burning more fuel.
I do prefer less power and less weight, makes things easier in the rain for an overall same speed.
I did a few runs on racing hards with more power, but it just empties the tank with increasing rate vs the speed gain.
Didnt try how much power can be gained when adding weight, but at least for me I doubt this is beneficial.
It all comes down on the total laps when the flag is ending the race.
57 laps on my clock, and I guess I could improve with skipping the intermediate and just doing 2-3 careful laps instead.
The weather isnt accuratly identical every time on my last 4 attempts now, but it always goes like
dry-interwet-dry-fullwet-dry
Simply switch to fullwet tyres on the 2nd, no guessing, no trying hard, just do it.
For reference: I just tried with racing hards (the free PP is invested into reducing rear aero, handling was still all fine, but increases speed while staying on good fuel economy this way) and skipped changing tyres on the first pit and not using intermediates for the first rain.
I again ran a total of 57 laps at the end.
I also tried adding weight for adding power and as expected, this is a stupid idea on this event
