But Leo is right and I mentioned this at MTH that one day (not sure who was on the chair with me). The drop zone method only works for the first hit in a line of features. From that first drop you need to make sure you have the right speed for the first jump but also enough (or more than enough) to carry you through the rest of the line. After you land the first hit, you don't get to "drop" in again, you can only speed check at that point.
I'm not saying the drop method is useless because it's not, but what's more important (and what the drop method is a proxy for) is gauging speed. You should be able to know, regardless of where you dropped in, whether you have enough, not enough, or too much speed for the next jump. Dropping helps you gauge that speed and puts somewhat of an upper bound on it, but that's it.
