" That is a horribly inaccurate way of creating your % upgraded statistic, for several reasons..."
All technically quite correct I'm sure. But the spirit of the original post was really just to show that despite all reports to the contrary, SOME Choice properties really do honor the upgrade benefit, there just wasn't any factual data showing where and when. I'm not sure anyone at Choice beyond the Revenue Managers for the specific properties could really tell us how often the benefit is extended.
Cheers!
