What was the true golden era of rallying?

How many teams participated full-time or part-time?

Before 1995 I've counted a team having done a full season when they have started in 7-8 rallies (depending on how many rallies you could count to your score that year).



Competitiveness can be measured by looking at how many of the teams managed to win a rally, finish on the podium or neither?



I have counted only one team per brand so the likes of Stobart do not count.

Also, I only counted the top class entries so for example Volkswagen in 1986-1987 doesn't count in.

Some one-offs were also left off but for example in 1985 it was difficult to leave out Renault who won their only start.
