11 Hour reduced rest rule

Sorry I’m not explaining myself very well,

I’m on about the amount of times you can reduce your daily rest period, as I see it as you can only do this x3 over a 2 week period,

So if your having less than 11 hours rest on say x4 occasions over a 2 week period will I get an infringement ? No matter if it’s one minute under the reduced requirement of 11 hours.

I hope that’s a bit clearer.
