Man, it has been a LOOOOONG time! Sorry have not been around.
In response - yes and no. If the fish are just biting at the tail, absolutely yes you can go through these baits quick!
But...when the fish are inhaling the bait, you can get up to 10-15 fish in my experience. I know Mike Tuck (pro angler up in NorCal) said he's gotten 20+ fish with a single bait but I haven't personally.
Also, so you know, I do quite a bit of boat team tournaments up here in NorCal and pound the Delta quite a bit and most guys use the Trashfish over the Berkeley imitation. It looks the same but the action is quite different.
Been a while or would attach a pic of some nice fish stuck last year on the Trashfish...
