Default Ignition timing Clarification

Having an argument with a friend about timing. Yes, have done a search. Yes I am useing a timing light. Yes, am jumping test connector. But he doesn't belive me.
Now assuming you are standing at the passenger fender looking straight at the dist:

If you turn the dist. clockwise (twards the front bumper), that would be retarding. The rpm's fall a little at idel.

If you turn the dist. counter clockwise (twards the firewall) , that would be advancing, rpm's pick up.

Is this correct? Or incorrect. Just looking for some clarification.

correct... think about it this way.. the (honda) engines turn backwards than most conventional motors.. meaning if you stand on the passenger side, the crank is rotating clockwise... With that in mind.. the cams are also rotating clockwise.

Since the distributor is attached to the intake cam, that means the rotor inside the distributor is also rotating clockwise.

Now the points inside the distributor cap are at FIXED locations inside the cap.. thus, if you think about it.. if you turn the points closer to the 'sparking point', then it will advance the timing right? And thus, turning the points 'closer' would mean turning the distributor towards the firewall - or counterclockwise.

Thus the rotor will touch the points sooner on each revolution.
