I managed to get through the steps to build the RWTST version of the transformer. I'm getting caught up on Step 14:

I have continuity between the secondaries. I also have continuity between the primary center tap and each of the two primary points on the left side. I do not have continuity between the two P points on the left side (i.e., the wires that were part of the hairpin loop before I cut it). Am I supposed to? Based on the wording in the instructions ("points P (P is for primary) should all show continuity to each other"), I assumed that I should have continuity between the two P points on the left side.

Separately, do I understand correctly that the tighter the wire is twisted, the closer I will get to optimum power? I was able to twist them quite tightly, but it made them brittle for completing the coil. I tried again with fresh wire but I'm concerned that it's not tight enough.
?
Thanks!
