Traction control difference between PTM 3&4

[BaylorCamaro]

Mode 3 – Traction control set on Sport 1, with stability control on and Magnetic Ride Control set on Sport.
Mode 4 – Traction control set on Sport 2, with stability control off and Magnetic Ride Control set on Sport.

Obviously the big difference between PTM 3 & 4 is whether or not stability control is on. However this is really the first time I've noticed the statement "Sport 1" & "Sport 2" in reference to traction control.

Any idea what differences Sport 1 traction control and Sport 2 control are? I'm assuming Sport 2 offers less computer input when the driver starts to break traction?

Oh I see, it's just the name they give PTM 3 and PTM 4.
