Sure, I agree that if everything is done exactly right, there is very little worry at all, as was the case of my LS. The worry has been that the person who did the tension setup might not have gotten it correct, and so there is the increased risk of skip, due to the particular design. Even Alfa realized that, thus the redesign.
I had the utmost faith that my LS was always set up correctly by Carlo, so I could run the timing belt for longer than many chose to, with no worries, as long as the belt remained in good condition.
