Don't use a chart for Construct 7, really...

[Maeka]

So, I came up with an even simpler way to do this mechanic.

This new way, you don't even have to count on your fingers. All you need to be able to do, is +1 a number and look at a chart. You can do that, right? Count from one to ten?

Get a little strip of paper, and write this on it:

1
2
3 (Threes)
4 (Fours)
5 (Fives, Prime)
6 (Threes)
7 (Prime)
8 (Fours)
9 (Threes)
10 (Fives)
11 (Prime)
12 (Threes, Fours)

Tape it to the side of your monitor.

When you get the HP Down debuff, run towards the left-most (the #1) circle, and face the boss's side of the room (don't face him directly because that'll be diagonal). Don't stand where the circle is going to pop, but right next to it.

In the meantime, look over at the little piece of paper you wrote this stuff on. Find your number on it.

Wait for the boss to tell you what he wants. Compare your number to the chart.

Strafe Right, and as you pass through Circle #1, count up one from your HP number and see if it meets the criteria.

If not, Strafe Right some more and as you pass through Circle #2, count up one more and check again.

Continue doing this until you meet the criteria. Stop in that circle.

Example:

You are given 4 and he wants Threes.

Stand near Circle #1.

Is "Threes" written after 4? No. Strafe right into Circle #1.
Count up to 5. Is "Threes" written after 5? No. Strafe Right into Circle #2.
Count up to 6. Is "Threes" written after 6? Yes. Stay in that circle.

That way, you don't even have to any kind of math at all, other than counting numbers <12.

EDIT: You know, since Construct 7 is a robot, you guys are lucky that you don't have to count in binary or hex. lol. I could only imagine the rage if they did that.
