controversial no doubt but i don't see any benefits to pre baiting it was probably invented by bait companies to sell more bait,watercraft goes out of the window if you have pre-conceptions and bait a swim a couple of days in advance of fishing it imo.With that many anglers baiting with similar baits you might as well turn up and find the fish flick them a stringer, they'll recognise it as food.
i see anglers pre-baiting heavily and they seem to end up moaning that someones jumped in their swim or they are always catching loads of bream.
all your effectively doing is paying a fortune to give yourself a little extra confidence.
