It's both. I just downloaded a KD card from TM, with 6 races, and also the KD races are merged in a separate TP card. Both cards opened in Spec160. Give it a try.
(Unfortunately, neither card opens in RDSS, mix of tracks bug
).
I'll be using Spec160 to work that stakes race, one of the BRIS Contest races. Room for 5 of us in Las Vegas!
