there are only 2 ranges on the FSS message. they are huge ranges. you can't just nail it down like 10-12 or 14-18... it could be 4 home visits or it could be 20. for sims, if you can look at their players and figure out if this is their top target or not, that is huge - their top target is so much more expensive to take than 2nd.
also note that because with higher prestige, you get more credit for your actions, at lower divisions, it is really hard to get to the tight FSS message. 30 home visits might not do it. so that message is more or less meaningless.
