Your dives were deco dives, from the looks of it. Mine are not (not for a couple more years, at least).
True, every one from Sports diver up is Decompression Qualified (Ocean Diver isn't - 20m maximum depth). However, not everyone will run a decompression dive. But now as a club, we recommend rich Nitrox in the afternoon, lean nitrox the following morning. (DDRC say your better bent on Nitrox than air)
