No no, it's a totally different thing. Here let me explain.

Let x represent the prices during busy times and y represent prices during slower times.

"Surge pricing" is when x > y (boo, everyone hates it, Wendy's is definitely not doing that)

"Dynamic pricing" is when y < x (totally different, consumer friendly, yay discounts)

So you see, x won't be greater than y, y will simply be less than x
