I'm still not really clear on why it matters. If anything, grooved rotor/pad combos have more friction surface :)

I just swapped pads last weekend for a track day, my rotors are grooved and should be replaced next time I have to replace my street pads, but once the pads are bedded in, they still grip amazingly well.

It essentially cuts life from the pads, it does not change your braking distance.

Just as bad in a few weeks seems like a bit of an overstatement then, unless you're replacing your pads based on their wear rate instead of how worn they are

Depending on how bad your disks are that can really add up.
