Wow this forum is so great. I have a 4000 rpm miss as well with my Effie. Vacuum secondaries also. Just to find the elusive time.

The other thing to keep in mind. I have the 6AL and Smiths tach. For whatever reason which I havent determined yet, at 4K, the tach reading starts to drop. Almost like a missing tach signal or something.
The engine is still running fine but to look at the tach it appears like the engine is cutting out.
Granted, Im sorry to say, I dont have the engine at 4K or over very often or for very long so it isnt really an inconvenience.
May be the issue is the tach and not the engine.
