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

[Masekase_Hurricane]

So I see people starting to make charts on how to handle that substract mechanic...

In all honesty, please try to understand the mechanic instead of using charts... it is nothing hard.
And also, because instead of helping, it looks like charts are actually making people even more confuse on how to handle said mechanic.
