How many degrees of a legend?

I was pretty pleased to be in just 2 degrees of Vincent, and Bill Clinton, the latter making me just 3 degrees of Barack Obama. But a chance conversation yesterday, reminiscing with a friend, gave me a big surprise.

When I was in the 6th Form at school (nowadays known as Post-16) it was common practice for schools to have modern language assistants. These were native speakers, students working as tutors to help school kids with conversational French, German, Spanish, etc. As I was studying French, I had regular small group or individual sessions with our French assistant, who happened to be Algerian. One day, he mentioned having met Che Guevara. I was too stunned to enquire further, but it now occurs to me -

I am 2 degrees of Che Guevara!

And as you know me, you are 3 degrees away.

Wow!
