Ignition timing on 83 sc

I had my distributor rebuilt last fall
The instructions l had with the rebuilt unit was to set timing at 16 to 20 btdc at idle

I set it that way and it seems to run fine except I have nothing to compare, so it may not be as fine as it should.
The Bentley manual shows timing set at 5 btdc at idle and 21+/- 3 at 6000 rpm.

Needless to say I am confused.

What do you tuners say?

It seems I also read (somewhere) that timing should be 36 btdc at 6000.

Can anyone enlighten me?

Thx
Hugh
