As far as the whole "Roll harder, Peterborough" comment goes, I'm not sure I understand how to take that.
Personally as a whitebelt, my game is changing as I get more comfortable with Jiu Jitsu. I know when I first started I was super spazztic, flinging limbs all over the place, whirling around like tornado, needlessly scrambling, etc. As I become more and more comfortable my general movements are slowing down, because I want them too. I have one year into Jiu Jitsu now and I am just starting to feel comfortable.
There are a few guys at our club who play a slow and steady game, where the pressure is one and you see things coming, but because of weight distribution, contact control, etc, there is not much you can do to stop whatever you see coming.
I have always been impressed by guys who roll like that, and I am trying to emulate that slow, steady, unstoppable pressure.
I can also be explosive and ultra fast if the game calls for that, but in general I make a concerted effort to roll under control and at pace that is slower than my old spazztic speed.
The dynamics of the matches change all the time. In my experience, two whitebelts tend to go harder and faster at each other than a whitebelt versus a senior belt. Typically the whitebelts don't want to tap to each other so the match intensity will escalate. I always try to slow things down when that happens.
Generally if a whitebelt rolls a higher belt/higher skilled player, the higher belt will set the match tempo anyways, and based on what I have experienced, it's a measured tempo.
So what I am saying is sometimes we roll easy, sometimes we roll "hard", but either way our rolling NEVER lacks in intensity in Peterborough.
