I am currently engaged in a massive test effort to understand such short-range leapers. It is slow going, though: there are many possible combinations of moves, especially if you drop the requirement for 8-fold symmetry. And I need at least 400 games to get an acceptable accuracy for the empirical piece value of a ertain piece type. Even then, the statistical (random) error in the piece values is about 0.1 Pawn, if I test them in pairs (to double the effect of any value difference). Your estimate seems reasonable, from what I have learned so far. 8-fold-symmetric SR compound leapers with N moves seem to have a value close to (30+5/8*N)*N, in centiPawn. That would evaluate to 640 for the Squirrel. And I expect the Squirrel to be one of the stronger such compounds, with this number of moves, because of the 'front' of 5 contiguous forward moves.
