Oh, a quick way to tell if a spin has turned into a spiral,

Should have thought the rapidly increasing wind noise and G forces
would rather give it away...

Some very experienced pilots have made the mistake of
interpreting a spiral dive as a spin. IIRC this was how
an Eta was lost during spin test (pilots bailed out OK).

So, its not necessarily so easy to distinguish,
especially in clean quiet fast gliders...
In the briefing prior I first flew an Antares I was
specifically warned on this...

Be careful out there,
