The wrestlers you mentioned are some of Kansas best wrestlers both past and current, and yes riding time may not have been a factor in these matches do to these wrestlers no willing to let it happen. If I was to guess knowing the style of these elite wrestlers you mentioned there would have been no riding time accumulated anyway.

On the other hand I have seen some great wrestlers get beat, because they were down by 1 or 2 points going into the 3rd period, and the bottom guy laid there, because he knew he had a stalling warning and a point to spare. with riding time there would not have been a point to spare, because 1 point for stalling, and 1 point for riding time.
