Chad,
10 per side seems about right. I helped my IA install the Kosola inertial real system in both front seats in my 260. It took us about 8-9 hours total. If we had to do it again, we could probably cut that down to 6-7. Keep in mind, that is for two people - 16-18 man hours. Granted, as a helper, I certainly did not contribute a full 8-9 hours of "billable labor".
That 8-9 hours did not include any fussing with the headliner as I already had it completely removed in preparation for new including new insulation. Between R&R on the plastic window trim, pulling down the headliner, reinstalling the headliner and touching up paint on the exposed rivets, I could see another 3-4 man hours. In addition, without the headliner competely removed, it probably slowed your installation. I also had no side windows at the time which helped.
If your headliner was left intact and you are happy with the appearance, I would not worry too much about an extra hour or two for the install. It sounds like they took their time to avoid screwing up the headliner.
Having installed both the Lenny Spall system in a previous 180 and the Kosola system in my current 260, you made a good choice going with Kosola.
