I looked at last weeks results and I was wondering how the streaks work?
The idea is to consecutively obtain 3 sub-15 averages over 3 weeks participating on this thread. If you do so, you 'graduate' and you're likely to be at a stage where you are truly sub-15! The 'streaks' is just a counter of how many consecutive sub-15 averages you have so far, incrementing by one every week you get a sub-15 average, and reset to 0 if your average is over 15 seconds. Hope this is relatively intuitive and makes sense!
