Couple of things. Just because there is a gap between 6th and 7th (for example) doesn’t mean there isn’t a back marker in the middle 1 lap down. This seems like a lottery of fastest inside the top 10 in the right place at the right time with enough sets of the fastest tyres available. No point in pitting if you only have mediums available and someone else has softs.
I think with the 3PU rule this season too I’d rather see the driver who has fastest lap (overall, not just top 10) then they get to choose a single component to have extra. Last race of the season....meh who cares. Fastest lap bragging rights?!
