You are welcome to, but I've addressed it a couple of times. I don't see where it lags (people saying "it isn't fast enough" doesn't help) and I have adjusted the clicking between animations to be pretty fast imo. It doesn't wait for animation to be finished, it clicks well before that - though apparently not fast enough. Haven't had the chance to find optimal rates with that.
I'll keep testing for sure, but as of now not too worried about it - esp with it being profitable, good xp and offered on the free version of this bot (aka if you're paying for spin flax on this bot, stop and go use the magics lite). Chances are if I get the spell up to anywhere near the speed that the wiki lists, it'll be removed from the free version and moved back to premium only like it was originally.
As for plank make, reread Harris' post. It isn't broken. He mentioned he was using a rune pouch. That's the reason it didn't work for him, rune pouch isn't and has never been supported.
