Agreed, but the restrictor size was increased to 34 mm from 32(ish) mm in 2 stages just before the race in a final round of BoP adjustments, turns out it was not enough and it is doubtful Porsche will be granted more...

Yes, they originally had 33mm , so they were increased by just 1mm. This was clearly not enough , given that Mercedes were allowed to keep their current BoP (due to profound sand bagging in the first 3 VLN races). If the regulators wanted to allow Mercedes to keep their current BoP, they should have increased Porsche's BoP by a significant margin/
