100 Push-Ups In 6 Weeks: Week 1, Day 2

Saturday was Week 1: Day 2 of the "100 Push-ups in 6 weeks" program (using the free Android App because I'm cheap and it was out there).

Week 1, Day 2 had the following - each with a 90-second rest in between:
6 push-ups
7 push-ups
6 push-ups
4 push-ups
7 push-ups (or more to max out - my max was 10)

My arms were noticeably sore on Sunday, which was a nice change.

I  noticed today that I was off on the Week/Day count. I counted the initial test as Week 1, Day 1 - but I'm seeing now that tonight's scheduled workout is labeled "Week 1, Day 3" which is what I thought I did on Saturday. However, the numbers are higher so it's definitely not what I did on Saturday. This bugs me to do a workout labeled "Day 3" on the first day of the week so I'm going to skip some rest days until I'm caught up. By Thursday I'll be back on track and I'll take my recommended rest days. Or maybe I won't. Heck, if I don't feel it causing any muscular issues, I might just stay on it as an every day program until it gets too difficult to do so and the rest days will be required instead of just recommended.
