MG TD TF 1500 - Spark advance

I read somewere that the distributor should be advanced one or two degrees beyond what is recommended in the workshop manual (TDC). Suppossedly, this is due to the higher octane gas which is sold today. What are your thoughts on this?

Russ -- I'm running about 5 deg. before TDC static with pertronix ignition. Seems to be fine, I don't hear any pinging (pinking).

Here is a link to 2 articles by Skip Burns. I followed his guidelines (I think I use the width of 6 dimes) to advance it about 10 degrees (BTDC).
Very good articles.
