The entnum 575 dist 335 given in the tutorial is just an example of /viewent output. You will see something different. Approach the flag look directly at it , open the console then type /viewent. The console should then give a result and on one line the words team_WOLF_checkpoint may appear. if it does then the value after entnum is the value you need for the action and node in the waypoint.
If you have trouble finding it you can also look for it in hobbits waypoint tool bsp reader provided the map does not have a custom script file. For some things /configstrings can be an alternate as well.
