I'm not aware of any stats regarding OIS vs BAR 97.
I measured emissions on a 2000 CAMARO that would have clearly
failed a BAR 97 Test.
I don't know if the BAR Gods "want to know" those STATS.
If it was humanly possible I would summon the BAR Chief and his
Engineers to my shop to prove my point.
I don't know but the BAR Gods might not be humble enough
to admit BAR OIS DAD test is Not More Effective then
Real Emissions testing.
I have never seen any data on this but I've been a mechanic professionally since 1990 and I can tell you with all absolute certainty but there's been a few vehicles just listening to them run that should have failed but because the monitors were good and all the components were there they passed

Does anyone no if there is any publications on how many cares pass the OIS test that would fail a BAR 97 test?

It cuts both ways. I can recall how many cars passed on Bar97 when 2 monitors were allowed with pending codes, that now fail now due to the extra running it takes to set all monitors needed.pending codes become hard codes. People were resetting check engine lights with out repairing them and running them with their cheap hand held scanner, and as soon there was 2 mon not set they drive in for smog, So I think iOS and the new monitor rules catch more cars or customers are forced to fix them instead of gaming the system. Dealers and shade tree were gaming system more than the regular customer. I know it’s far from perfect but that’s what we got now
