AG * > Inflation requires a *minimum* starting size size (which can be microscopic), and *minimum* duration of inflation (which can be as little as ~100 doublings) taking as little as 10^-35 seconds, but as far as I know these are only the minimums to be congruent with observations. Inflation, by no means requires the preinflation universe to be tiny, nor the time period of inflation to be short. Either the preinflation size could be unoundedly large, or the inflation duration could be unboundedly long.
