It's always a good idea to plot the clutch slip by using gear ratio.
That way you can identify and quantify the slip.
For example, the big circle is possibly a lean spot in the cal causing a reduction in power whereas the other circle is clutch slip for sure.
Gear ratio compares wheel speed with engine speed. So a dip in power (big circle) graph is not usually slip as with the screwy graph (small circle) indication a lost relationship between wheel and engine rpms.
