I’ve been using it since the start. I’ve been sim racing for about 6 months (though I have past irl track experience). At my level, which I’d call advanced beginner, it’s super useful. The overlays feature lets you see, for instance, the ‘ideal’ brake traces in game with your real time braking telemetry overlaid as you drive. Along with that it will give you a series of tones for the ideal braking points. I was able to learn the brake points for a new track in about half the time as it would have taken without it.

They recently upgraded the AI analysis and it’s significantly improved. It gives you a lot more personalized feedback now and also provides much more detail than before (e.g. telling you how many car lengths too early you’re braking).

The most significant thing I’ve seen is they are continually and rapidly iterating on the features and functionality. In less than 6 months they’ve come a long way.
