Can I let battery drain longer than 5 hours as part of power calibration when replacing the battery

I've replaced the battery on my 2015 MacBook Air. When doing the power calibration steps, it says to charge the battery to full, let it charge for 2 more hours, then unplug the power, let it shut off, and then wait "at least 5 hours" so the battery drains all the way. I did this last night and when I went to bed at around 11:00, the battery was at 75%. This morning at 9 am my laptop was off. But I can't tell if it reached the 5-hour mark. My question is, can I wait until later this afternoon before plugging it back in to do the final charge? Since the instructions say "at least 5 hours", what if I wait 10 hours? Will that cause any issues? Thanks.
