As per hold entries, I have a simple way, but whatever works for you is what you should go with. I teach that, for the standard holding pattern, if the hold side heading is LESS than your heading, the entry is Parallel. If the holding heading is GREATER than your heading, the entry is Tear Drop. If it's in between, go with Teardrop. If it's reatively aft, it would be a direct entry. Example: Hold on the 270 DEG Radial, your heading is 180 DEG, the entry is Teardrop. If it's a NONSTANDARD pattern, reverse the Teardrop and Parrallel for the above method. It's confusing in the beginning, but if you drill yourself, it will become easier than trying to do the 3 finger split. Hope this helps, but also draw it out on paper to see for yourself.
