Tach filter needed for ready to run distributor?

Tach adapters come in two basic types - I've designed one of each before. Filters take a signal off the coil, remove high voltage spikes and short pulses, and send out a cleaned up 0-12 volt signal. You use these if the tach isn't steady, reads too high, or for some non tach application like triggering an ECU off a line lock. If a ready to run distributor uses a tach filter, it's one of these - and it is likely to work without it.

Then you have tach adapters that almost do the opposite. These take a low voltage pulse and use an indicator that acts like the primary side of a coil with no secondary, generating short high voltage pulses. You see these when using a low voltage tach output off a CDI or fuel injection when a stock tach won't trigger. The distributor in the original post shouldn't need this.
