You know that Motec i2 does all you mentioned (and way more of course).Fair point. Motec is waaaayyyy too complicated for many of us. I use RaceLogic data and mapping overlays for my real track time. It's great because it gives both the lap trace, lines used, braking points etc (gear, throttle and brake position if connected to the ECU). This I find useful as a learning tool, it can also easily be overlayed onto video too. I think many racing gamers would find data like this useful - the lap trace/braking points, apex and exit clipping points overlayed onto a trackmap, especially if they could compare this with a best or ideal.
I'm sure Motec also gives all that data and a lot more too. It's great that Kunos added it in in for those who want to use it but it's a step too far for me.
I'd really like to know if it does make people faster. There are plenty of fast times out there before/without MOTEC data. I doubt it's going to change anyone from average to alien! Marginal gains for the most dedicated though, yes I can appreciate it could help with that.
You just have to build your own worksheets (you can always simplify them and aid with visualization).
The initial hurdle is first to learn how the Motec i2 software works as it is simply the most powerful and most flexible data analysis software on the market - the initial learning curve for beginners is steep.
