right now it feels like it takes an hour to fix one bug or so, i don't know how many people are involved with the QA testing but at the moment progress is really slow
It quite honestly depends on the severity of the bug, how easy it is to reproduce, and how hard it is to fix. Granted, I've worked with much more complex platforms, but I've seen developers, groups of developers mind boggled for weeks over a single bug. It was critical, show stopping when it occurred, but it was tough to reproduce, and even tougher to find what was causing the unintended behavior. Once QA figured out how to reliably reproduce, the fix took minutes, and testing took just a few hours.
And then I've seen bugs that were tiny, but required massive overhaul of systems to fix.
So if its a terrible bug, it could still be the same bug when it was 0/1 bugs as 170/171 bugs that is causing them to need time to fix.
