Before the particulars, I'd like even a confirmation that changing one's ad text can result in instantly higher CPC due to no ad CTR history?

This is a fundamental question one needs the answer to in order to proceed in logical fashion in managing one's own advertising budget.

I undertand the need for the secerecy of algo details, but the basics of how pricing works is not something I am happy with Google witholding.

Why can't this simple question receive an answer?
