I think I didnt explain it clearly.. let me make it clear..

1. The database we are using is having BooleanField for it!! so, cant do
anything
2. I am not looking for sorting algorithms .. just simple math :) It sounds
crazy but let me describe my confusion

lets have 3 users with

[null, null, null]
reputation = 0

[T, - - ]
rept = 1

[T T T]
rept = 3

[T T F]
rept = 1 (its jumping from 3 to 1 -->but generally, we observe only
decrease in 1 right?)

[T T F]
rept = 3 (its jumping from 1 to 3)

These jumpings are common? or my logic is going any wrong?
