Also we can lose an extra guy before bottling.
As per Core Rules - Dividing (page 22) fractions are always rounded up in Shadow War, so half of 13 is 7. It's a moot point as I don't think there's an efficient way to end up with the team composition I outlined anyway.
That 13th member pushing you over to needing a 4th model downed/out of action before bottle tests begin is a much bigger deal - good spot.
I'd be very interested in hearing thoughts from the orbital on initial teams and purchasing strategies now that we can't quite afford a whole team in the initial budget. This change makes me want to consider the Scavenger skill (+50 recruit/rearm points) and spending the first cache for +100 recruit points much more highly.
