Two weeks ago I was in the mountains climbing. Before I left I weighed bike and myself, both in riding condition. There is a 10 km climb with an almost constant grade; about 7%.:

I resetted my Garmin at the bottom of the climb. At the top I looked at the average power I managed and I calculated my climbing time within 30 seconds accuracy from the average power and weight.

I assume your calculations were done the simplest way, ignoring any aero
drag, right? Aero drag would be minimal at normal climbing speeds for a
7% grade.
