Not trying to deter you, I like to say this to help circumvent any further disappointment. From Mr Boothey's recent advice I now believe these two numbers are *individual* cutoffs not combo i.e. either one below would be excluded but both above is not necessarily sufficient for an invite, you also need to meet the combo cutoff.
It still leaves the question why a poster with IB40 (~98.3) & 181 got a round 2 invite, maybe they have EAS?
