KW-V2....So you've got some adjustability, and the more adjustability there is, the trickier it is to find that sweet spot. Also, having paid for a system with that adjustability, why not get the most out of it. I'm not saying you couldn't organise a p!ss-up in a brewery but only that IMO trial and error won't necessarily find you the best setup it's capable of being.
Another factor though is that you might not have a couple of hundred squid spare right now to pay an 'expert'.
Of course I may be speaking out of turn and you may have setup many cars in the past and know exactly what you're doing.
This is possibly reading a wee bit insulting(?) - It's really not meant to be! It's meant to just be sharing/expressing an opinion as to how to achieve the optimum setup.
