do you want to say

1. scan the key without worriying if it is bouncing. if your ods are in favour you will get it when its is down.which is the best case and in this case nop need to wait for 30 msescs and you get the key instantly.

2. in worst case if you missed it falsely on first scan you will certainly read it correctly if it is down.

if i'm right this can be done following way

1. read the key if it is down go to step 3.
2. perform debaouncing delay. go to step 1
3. exit

in worst case it is similar to our old method.

in best case you will save 100 msecs. but this saving is not significant as you must delay again to achieve certain repeat rate of the keystrokes. this may be benificial if you dont want to repeat the keystroke and use it only once.
