Then ít gets cancelled for weather, then you try to get back on the schedule in maybe 6 weeks. I know this because my son had this happen in last 3 years. Private twice. Instrument twice, commercial 3 times.
When I was flying a jump plane 182 many years ago, I remember at 500 feet reducing rpm by 100. But, throttle stayed wide open till altitude was reached usually 7500 feet.
