Honestly we scripters that have blast furnace bots are all at the similar rate of profit/exp per hour, the wiki is just wrong, I cannot replicate it by hand (tick perfect or not) and have always challenged others to try even get near wiki rates by hand just to prove it's possible, but I don't think it is possible without using any special plugins on runelite like bird's eye view etc. With that being said I'm always on the lookout to improve speed and reduce delays wherever possible, so if you notice any areas which are super slow feel free to shout at me XD
With that being said, we also need to take into consideration that perfect speeds (and tick speeds) is too robotic and will most likely result in bans anyway, so it's not worth it.
