I should clarify.
I hand in an attendance card every time I train. This is also logged by a computer, so ready access to a total count of my attendance is seconds away.
I no longer participate in the tip card process, which is a card that students are expected to present to the instructor when they have met the requirements for their next stripe. Mine was never refiled after my last striping I assume by mistake, and rather than bring it up and continue to chase the next stripe, I just continued on my training as usual. I'd actually decided after that stripe that I was going to stop the process regardless. The fact that it was never replaced was serendipitous.
Maybe I'm wrong though, maybe it's being withheld from me intentionally for some possible slight! :O Haha. Now that would be politics.
Promotions at my school seem to be 100% reliant on stripe adherence. I've never seen a 3 striper get the next belt. Of course, I'm probably the first to consciously opt out of striping at my school. People likely just assume that this is a part of Jiu Jitsu and how it is done everywhere.
