Well, when you have -/+ seconds, that could give you odd results. As if you're doing HGSS, the calls will have multiple seeds on different seeds.
For instance if you have KPPEEEPPKE, and you have +/- 9 seconds. You will have about 19 different seeds with that call order. And it will choose the +9 second one as it's the closest to the top. Since we are eliminating all but 1 of those different call orders. It will give the correct results every time. As ZOMGtimer hits the second effectively, and I'm sure you do as well. We are just getting rid of the useless data.
So now that you have only 1 seed with that call order, it makes your life simple as it will always tell you the correct delay you're hitting.
Sleepy time for me. Good night. Oyasumi Nasai.
