"Otherwise don't bother I would just as well wear a white belt forever." - smart
This is how it should be, train your positions, work your cardio, rep out the moves that come easy, rep the ones that are hard 10 times more. This belt thread is a waste of time, progress in BJJ is beyond winning and beyond belt colour.
Just train guys, that's all that will ever matter, you'll see how little all this "progress bar" shit really means. The best thing about Jiu Jitsu is your friends, and training so hard, and so much, that your think you're gonna pass out, and all you have left is your technique when your strength is gone.
