I had a pop at building Rand using the supporting character rules. The triad plus Scotty are probably the easiest to build as main characters so I might try supporting character versions of the others as well. Since Rand has relatively few appearances, her advancement was fairly easy. I expect if I stick to significant appearances for the others, I might end up with about the same.
I tried to build her heading towards her appearance in the Motion Picture as a CPO in engineering while retaining some generic utility as an assistant for Kirk. She can scream out a warning, point out the obvious, fix a transporter, provide a general level of security support, and plug away in the background keeping things running. I cheated a bit since I adopted a couple of appearances that were intended for Rand that never made it onto the screen (Galileo 7 and City on the Edge of Forever) since they both featured her modifying tech in a crisis and I thought the spirit of that was well reflected by the Jury Rig talent. She has two further appearances that I ignored (Naked Time - where she gets sexually harassed and flies the ship; and Conscience of the King - where she has no lines but sizes up Lenore in a heartbeat) so you could tweak her a bit more but I felt that those appearances were already reflected in her stats without the need to add anything.
It would also be possible to build her with more of a security slant. It’s not as reflected in the stories but this is quite possibly purely to do with the sexism of the show. One other possibility not seen at this point is that she becomes a communications officer (Draft script of TMP, STIV, STVI) so adding another focus there could help her sub for Uhura on the ship while she goes off and has fun.
