IOSleep vs IODelay

Hello developers,
I need to poll a status register for a condition that can take from 32us up to 16ms depending on a number of entries.
I was using IOSleep( max(1, num * 32 / 1000) ) in loop while checking for the condition.
It works but I was wondering if I should use IODelay when num is small?

int loop = 4;
int num;
while ( --loop && !condition(&num) )
{
if (num < 20)
IODelay(num * 32);
else
IOSleep( max(1, num * 32 / 1000) );
}

Or should I just poll the condition with no sleep, no delay when num is small, and use IOSleep when num is above 31?
Thanks for your advice,
Anthony
