Looking at China. From last year’s qualifying lap it’s about 60% Max torque demand and 15% zero ( harder to measure but a ballpark) in a 90 minute race that would be 90kg at 100 kg/hr leaving 15kg for the 25% part throttle, which doesn’t seem enough.
Perhaps another reason for not needing the full quantity is the tyres. Running max available power would likely reduce their life unacceptably so they don’t run up to the flow limits or approach the max load.
An increase to 110 kg may change things at one or 2 circuits but in general if they want to encourage pit stops by having limited durability tyres then teams will always short fill as much as possible.
That is why I make that comment.
However, they could make more power now by going up to the limit and use the full 105 kg allowed, but they don’t. So if you removed the flow limit but kept the quantity restriction they might use fuel up to the limit but I don’t think it’s a given. They have other resources to manage, tyres and drive train components.
