The allowable rpm drop for each is?

Explanation:
During an engine run-up, you test ignition performance by disconnecting one magneto at a time and watching the engine speed. A small RPM drop is normal, but there’s a maximum limit to ensure the ignition system is healthy. For each magneto, the allowable drop is 125 rpm. This means when you run on a single magneto, the RPM should not fall more than about 125 rpm. If it does, it can indicate ignition issues such as worn plugs, fouled plugs, weak leads, or timing concerns that warrant inspection. The other values are either higher or lower than this standard check, so they wouldn’t be the typical limit used in a standard magneto check.
