In regards to phone calls....
---What if they had planned on meeting up to chat (or whatever) but didn't want anyone else to know they were "friends". Maybe he left first---walking........ then she left--driving and picked him up along the way to his apartment. Maybe the number was a number he gave her or what she thought his cell was-- maybe trying to get ahold of him to see "where he was so she could pick him up". Does that make sense? Whatcha think?
It occurred to me that she left, then for some odd reason tried to call him, even though they had just seen each other at work and the need to call to set up a meeting would seem pointless.
Especially since it's only about 3 blocks drive (or walk) from the Academy to the apartments on Okanogan. That does still fall within the rather obscure description of "minutes" from the time she departed the parking lot. But I'd be shocked if enough minutes for her to get into his apartment and whacked on the head and thus incapacitated.
If that WERE the case, it puts premeditation right back on the table for me.
Why would she pick him up for such a short walk? Only thing I can come up with is the plan was to head someplace other than his apartment, but then changed plans. Maybe he "forgot" something, so they turned around (maybe were driving toward the boat launch) to go back to his place.
You have two people in the car, and one of them dialed that phone.
OR, she'd never been to that bldg before and somehow got lost in only 3 blocks? Or forgot the unit number he was in.
I know LE stated they looked at any other possible "close" number, but did they also look at transposed digits? Doesn't take much dyslexia to do that.
Maybe the prefix was COMPLETELY wrong and it should have been one for a landline, not cell. But Mac was the type who lived on that phone, and no doubt dialed a lot of people with 884 (and 881) prefixes in the Wenatchee area.
Perhaps, if she indeed dialed it, as I think (for now) she did, it was to the NEXT place she planned to stop after "apparently" driving over to the Okanogan address. Nobody has reported seeing her anywhere after she left the Academy, so I doubt she stopped, at least for more than a moment, anywhere before meeting up with CW.
Shoot, I could flow chart this thing all day and come up with a dozen options.
As far as the phone number, if she either transposed any two digits, or was completely off on the prefix, whoa. I can't even do the math on that one for the potential for different numbers it could be. If she did both -- got prefix confused AND transposed two or more digits in the last 4 -- have they really run all those possibilities?
She knew people in Tacoma. Maybe she dialed 509 when she meant to dial 253? Both 884 and 881 cell phone prefixes exist there as well. Probably also in other WA area codes, though I haven't looked.

If the wrong number(s) LE thinks they are have no connection to Mac, nor to CW, then who was she (or he) calling, and why? We may never know, and in the scheme of things, probably nothing needed to a conviction anyway. But sure trying to understand how she drove away from the Academy very much alive and was found deceased several days later at Crescent Bar.
The how and why are what is needed to understand how this horrific murder took Mac away from her family and friends.
