Anecdotal evidence does not equal facts.

I had about a 60% CPU success rate last year as a Plat. There are 1K's that have a CPU rate under 10%.

Both are anecdotal evidence, but to be presented to another pax as "fact" and "this is how your experience will be" is misleading. There are a multitude of variables that impact a flyer's experience with any airline.

As I said, if the OP's anecdotal evidence has been good enough for him/her to continue to shift more business to UA, your anecdotal evidence (and mine as well) is irrelevant.
