And your setup is intake camshaft from Tipo 16V and exhaust from original intake one, right?
From how I understand your measurements and as per below diagram
LobeLiftLarge.gif
They are for "Base Circle" and "Base Circle and Lobe Lift", correct?
If so the difference have to be as much as lift difference if base circle is the same. So specified lift of 10.15 for Tipo 16V camshaft and 8.6 for original intake one mean difference something around 1.5mm.
Generally speaking measuring camshafts with precision of integer (no part after decimal) is not accurate.
