Well One suggestion would be to create 2 counters for ex:
x = 500 ' whatever the ammount of steps u want
i = 0
j = 0
do until i = x
''' your code is excuted here
i = i + 1
j = j + i '' example value j grows much faster then i
'' whatever other algporithm u want to implement could be multiplied by j or whatever u need to do
i = j ' if you want your loop to skip some steps
loop
It is just a thought, but you can base something on this algorithm, also you can manipulate teh values of i and j or any ammount of variables as the loop is iterating
all you really have to do is come up with an algorithm for how man y steps to skip
hope this helps, or atleast gives u an idea in the right direction
