We found before "hawk eye" "stalker sport" radar gun were used in international cricket if so where exactly the gun was positioned at the stadium and at what angle & height?How much angle error must be fed to the gun?
What grade of players are you testing? 1st grade players can reach 125 / 130.
Lower grades can only reach 115kms even though they think they are much faster.

Yes the spin sounds low at 65Kms

Did you try setting it up to the side of the net or even behind the bowler just to see the difference.

Last point I think 95kms would be quite a quick spin delivery.
