About using streaks in app and sites

Nobody asked, but here is my little opinion on streaks. Years ago I was using an exercise app. I was on day 700 or so - what an excellent streak, oh joy! an Internet point that means nothing - I wasn't excited about it until it was taken away. One day a life event happened where I simply wasn't able to do the exercise that day. I lost my streak. The next day I open the app and I'm back down to zero 0 zilch nada - 700+ days wasted (you don't feel it until it's gone) I closed the app and never opened it again. Since I occasionally make things, this got me thinking about how I would do it. Here's how: Instead of continuous streaks, count 100 day streaks in blocks and goal is to accumulate blocks that are never taken away. ie: Derek has 4 100 days streaks. That way if I miss a day, I don't lose all those 100 day blocks, and I just start counting a new 100 day block. Maybe someone is already doing this.
