Rubbing the rack on the cloth probably had some (but small) effect.
The larger effect was that the Tournament Director racked the balls. You don't accuse the TD (Ken Shuman, no less) of trying to give you a slug rack. He racks the balls and then you break. You don't tell Ken to re-rack the balls.
Here's what's always worked for me. Place the one-ball on the spot in a place where it "rests". Put the triangle over the rack area and snug it up closely to the one-ball without moving the one-ball. The whole trick is not to fight the one-ball. It will naturally set up in the best place so don't move it.
After you've got the triangle snugged up to the one-ball, place the other balls carefully in the rack, row by row, making sure not to move the one-ball. You'll find this solves most racking problems because you're not arguing with the one-ball.
It's like I do in dog training: figure out what the dog wants to do...and then train him to do that. Figure out where the one-ball wants to sit and then work around that.
