The only explanation I can offer is this:
The nominal speed of the free power turbine (n2) is 15,000 rpm.

I’m guessing that 300-800 rpm is so low on the range of the pickup that the readings may be a bit unstable.

On the other hand, for this test the power tubine has no load, so it could gain speed very quickly. But coastdown would be slower…

at 1:00, on the monitor, the n2 window is just bugging or why is it hopping?

Tiny yes, but still 4,700 shaft horsepower!
