The flight plan and prediction tolerance settings are inconsistent

[eggrobin]

The flight plan tolerance is in powers of 2, whereas the prediction tolerance is in powers of 10. I suspect this is because the prediction setting was originally persisted in the C# only, so that it was convenient to save an index into an array of powers of 10, but since the flight plan setting started out persisted in the C++ as a Length, powers of 2 were easier because of the exact *= and /=.
