Well, BPs is kind of an easier to evaluate and observe metric that is more skill oriented.

Revenue?

Like, you'd need to do RPH over straight revenue, as people in higher end stores will outright win. And, even then, the numbers favor higher end stores.

Taking care of customers?

How do you quantify that?

NPS?

I've legitimately talked to people who knew people who lost Achievers in the past when NPS was a metric due to a bad comment. Imagine getting 100 good ones and losing because you got one customer that waited too long. That is... just extremely demoralizing.

I get we're going for the memes, but at least we all have equal opportunities, at least in theory, for a BP.
