I just see a lot of traction control intervention, even in moderate throttle applications. And if I’m getting onto a highway, I would think I could push the accelerator most of the way down and have the car get going quickly.

I’m not mashing the throttle - but the car wiggles and hesitates, with the traction control light blinking, between 1-2 and 2-3 gears, at least it does for me.
DSC intervention doesn't necessarily mean the car can't put the power down. I agree with the other member above that it's overly exaggerated. DSC is way too restrictive in F80/F82 even in Euro MDM! I used to drive in MDM (for the first 6mos of ownership) then switched to DSC off. It's night and day difference. I have PSS 295s in the back and they slip only in in 1st gear if I straight out floor it instead of gradually increase the throttle. If I floor in 2nd and 3rd it just grips with no drama ( dsc fully off and on a straight line). Never experienced difficulty of putting the power down at the track either. In fact, my lap times are 2sec faster with DSC fully off than in MDM at Laguna Seca. I think a lot of people floor it when DSC or MDM is on and complain about power delivery. F8x doesn't grip like an AWD car but it's not nearly as bad as described here either.
In my car with 285s out back I was like YES! this is way better.

If you can manage to fit 315s out back , yours won't slip any more at all in first. . I'm also confident you will *then* realize that you aren't actually getting all the power down currently. Ask me how I know.

Lap times with DSC off should definitely be quicker than MDM as the latter mode employs braking of the rear wheels , along with reducing the power of the motor to maintain traction at the rear. A person that drives very smoothly can avoid the car using the brakes at the rear but usually the power being backed off is still an issue. For example at Barber Motorsports park, for me coming out of the esses onto the back straight you absolutely need 100 percent power but the car will never let you get full throttle in MDM mode because one needs to accelerate from the apex to track out and the car is at an angle still. It's one of those places where more power actually helps you as a driver, and the car is still backing out of the throttle. I would imagine coming out of the corkscrew at lacuna would be similar.
Personal skill aside, the faster driver will be going through that turn without the DSC even engaging because they will be at the perfect speed and angle to take the turn with maximum grip and no loss of traction as opposed to the driver who is correcting with the throttle. The second driver might be faster with DSC off compared to their times with DSC on, but he would be even faster if he didn't engage DSC at all, even if it was on. In theory anyway.
