you must be joking?
a rbs supports more than one transaction, actually the extents inside a RBS supports more than one transaction, XACTS means active transaction going in each RBS, if I have 40 extents in a RBS I can perfectly have more than 1, 2, 3, 40, 80 or even more transactions concurrently depending on transaction size

If we base on strategy in a system with 200 concurrent transactions we would have to create 200 RBS?

If you see values > 0 in WAITS then you may consider adding more RBS but from the statistics pasted the wait is minimal
