@Riot | Reworking the Crit Chance Formula

Hey 'Riot' I'd like to propose a new way of Critical Striking. I'll just start with examples. I'll start easy and then I might do harder ones.

So scenario A :
You were afk the first 60 Minutes of the Match so when you spawn you're level 1 and have enough money to buy Infinity Edge.

That means you have 25 % Crit Chance and 0,6 Attack Speed.
So when you attack you generate a number between 1 and 100, if the number is 25 or beneath, you perform a critical strike. HOWEVER if you get a number higher aka you do not critically strike you activate the more complicated formula. So now for the next X seconds it takes you to hypothetically get 1 critical strike you get an ensurence, that if the time you needed to get 1 critical strike and you didn't get one is over you automatically get one for your next attack.
Do you get it so far ? I'll try making it simpler.
Step 1 : You attack and you crit = nothing happens.
Step 2 : You attack and you don't -> 25% crit = 1/4 attacks is a crit. Time needed to perform 3 attacks ( 1/X-1 ) is [0,6attackspeed -> ( mirror worth )] 10/6 = 1,66 times 3 = 5 seconds. That means if you perform an attack in the next 6 (+ 1 second for the attack animation) seconds and you don't critically strike the calculation is reset.
Step 3 : You attack and you don't crit -> Time needed to perform 2 attacks instead of 3 ( -> -1 ) = 3,33 seconds. If you don't critically strike in the next 4,33 seconds the calculation is reset.
Step 4 : You attack and you don't crit -> Time need to perform 1 attack instead of 2 ( -> -1 ) = 1,66 seconds. If you don't critically strike in the next 2,66 seconds you gain 100 % crit strike for 2,66 seconds. (You don't know this though. Since the calculation isn't written anywhere in your screen.)
Extra : If you don't ever attack in the time given the calculation is canceled. If you critically strike it is also canceled.

Is this enough for explanation or should I add an example with more crit chance, once with more atk speed and one with both ?
In cases of attack speed enhancement at step 2 or 3 you can either adjust the formula or leave it as is and make Tristana the ultimate criter :D Because then attackspeed enhancements would mean crit chance enhancement.
