Yes my wife trains hard. She trained up until a week before our first son was born and she is 6 mos pregnant now and still trains (very restricted, mostly forms and structured partner training).
As far as our Aikijujutsu training. Kamishin Ryu is organized very similar to Hakko Ryu in that it has Shodan, Nidan, etc waza lists. These lists are relatively short lists (usually 15-25 techniques per list) plus each techniques variations and different applications. We do not use the Aikido (or Aikijujutsu) style Ikkajo or Ikkyo. Our first technique is called Kamishin Shomei Odori then Kote Shomei Odori, Te Hana Odori, etc. Each name is given as a sort of identifier of the technique layout or underlying principle.
As far as PP training it begins roughly around the Gokyu step. Basic pressure point assists to the locking technique, usually at this point for pinning techniques. Usually Sankyu level we get into the beginnings of striking PP techniques. These levels are the basic levels, at times a lower student may be shown a technique involving PP, but the deeper explanations are skipped until the student is more proficient.
Kamishin Ryu does not go as deeply into the PP/Meridian training as does Hakko Ryu. From what I have seen of Hakko Ryu it is a fundemental part of the training, in Kamishin Ryu it is more of a "helping assist" to the waza.
