Exposing in cross-processing

I got some Ektachrome (expired) 100 as a gift. The guy who gave them to me told me to rate at 200 ASA. I really don't understand why to do this (but listened to him and got cool enough results). I tend to think the frames I shot leaning more towards a 120 ASA speed were a little muddier. Any thoughts on why might this have hapenned? I'm a little confused because many people sugest (online) to overexpose expired E-6 rolls a little, and I don't really know whose advice to follow in other emulsions further cases, I'm getting some Provia in a few days.

Hello elmartinj. Can you post the images for comparison? It will be easier for people to give suggestions.

Provia cross processes more easily than Ektachrome -- less saturation, and the contrast isn't out of control. I believe your source might have had that same experience, and thought to underexpose the film slightly (his suggestion of 200) to compensate. Personally, I think you're better off underdeveloping -- pulling the film at say 2:45 instead of 3:15 -- than underexposing. Will you be printing or scanning the resulting negatives?

Scanning as of now, I'll post to flickr and send a link when done
