Campy Chorus Compact question

[velogirl]

I often have to trim the left (front) twice!

I've been riding Campy record (first with a double and then with a compact double) for many years. It sounds to me that when you're on the small ring, you need to trim as you get to the smaller cogs on the cassette. The nice thing with a 10-speed double is that you can get away without doing this most of the time. However, if you don't trim on the small ring, you will indeed need to shift twice to get the chain to move to the big ring.
