I am curious how you broke down how much time you spent authoring different aspects of your customs. I feel like I spend way too much time testing, but that's probably because I'm a Wii user and there's no easy way to do it. I'm jealous of those low testing hours! Also curious how you computed how much time CAT saved you.
A. Thanks! I've spent a good portion of my life "loving shiz like this" too, so I spent another good portion teaching myself how to do it. =-)
B. You'll get to 50, I'm sure of it!
C. I didn't use exact numbers, as I never punched a clock; however, I used averages balanced by the learning curve at the beginning and supplemented by efficiencies I gained as I went. Thus the average. I also don't test every instrument, as it's almost impossible for me to play some of those crazy guitar riffs and solos. I understand the concept, but my coordination with that plastic instrument is middling at best. I've gotten good at authoring drums and vocals, so the play test on those go quick. Usually it's minor alterations unless I've totally screwed something up good. Thus, the average numbers.
D. I use CAT sparingly. Mostly because I'm a control freak with certain things. So I really only use it to do reductions, vocal overdrive and drum animations. That one I did a straight calculation on since it's takes roughly the same time every time. Sometimes I have to adjust things more than others, but it's pretty consistent.
