docs: Create the buckets after warmup time.
  Can be overridden to customize buckets configuration.
  By default buckets are create with:<ul>
  <li>Min: stopwatch min-10% rounded to inferior millisecond</li>
  <li>Max: stopwatch max+10 rounded to superior millisecond</li>
  <li>Nb buckets: {@link #bucketNb}
