I can't understand how this has solved the problem really, yes I understand there is a restriction on the amount of time so you cant say one day. But 1 week is still up there, yes a week is good in recovery but isn't this just as competitive as some people will have the lowest bracelet able.
Wouldn't it be better to just have a ban on a certain time of recovery that is believed to be competitive or triggering as presented by the bracelets. Or a complete ban , or just the bracelets with the beads no writing ... as these require greater brain work than simply looking and seeing one week.
Maybe different colours could be representive of weeks to months. Then if you glance at someones signature you dont see it automatically but have to have a little think.
This is my opinion but I do think you have tried to eradicate it somewhat.
