Well, re: "where'd they go", thats not a bad thing if they players did it right. Also, the time it takes to actual traverse somewhere is oft forgotten, as well as the actual working with the macguffin or what not.
Real Life example: a direct action team in a western country decided to cooperate with civil authorities during a recent terrorism drill. They were supposed to test a nuclear plant's defenses. They had to get through a chain link fence with wire on it, cross the open ground, enter the building, find the control room, and then simulate starting a meltdown.
Suffice to say that they had made it to the control room and set the simulated charges to blow the doors open in about 120 seconds. Most people couldn't have sprinted the distance involved in 120 seconds without things like fences in the way. It wasn't the breaching the fence, or entering the doors, or "killing" the guards, or slapping down the charges that slowed these guys down the most - it was just covering the distance. Actually "starting the meltdown" took a bit longer
Suffice to say, if said highly prestigious direct action team took two minutes to breach a real site, there's no reason shadowrunners should get a free pass on running through a corporate office. I'm pretty sure 25m per turn does not apply to "straight up the stairs for 15 stories" at least not without some serious athletics tests.
Finally: even if they get out, so long as you have surveillance tag on them leaving, as corp sec you've got until the meet with the johnson to figure out an answer. Be that 30 minutes or 3 days, its all the time in the world to drop the hammer, or let the KE/Star do it for you.
