Then all you need is to have a positive WLR, and it will eventually get you up.
Tiers would require a different amount of maintaining WLR -- i.e. T5 = 0.6, T4 = 0.80, T3 = 1.0, T2 = 1.20, T1 = 1.4.
That means, you only need to win 50% of your matches to attain/retain T3. You need to win 70% of your matches to attain/retain T1, and you only need to win 40% of your matches to attain/retain T4.
Every 10 matches is measured, and adds or takes away from the Tier Bar.
