Don't use my times - I'm a hack. And half of my times are in other peoples cars. Use JP's times for a better indication. Whats he - 43's at EC and 45's at PI - both of those are "grip" tracks which I think is similar to OP right. (not like say Sandown which is purely HP).
So having a look at Johns times at OP and then going by what the "fast" guys do at PI an EC do I reckon a time around 1.12 is going to be pretty damn competative.
