The excess energy change is because I had Seekers and Traces being cast at 40+, which tends to make Scrywalls and other countermeasures a joke. Often not that hard for a group of PCs to come up with 80 energy for a single casting of a spell. I've been thinking about modifying it further and using the same chart for both.
The first one is just the Speed/Range table shifted by a row, and reading "Yards" as "Multipliers." The second one is the same, with the +20%, +40%, and +60% options added.
