Some are easier than others, basically it depends on how well the original chart is. I was considering adding them to my collection as well so I will have a look at them, but to better answer your question – they all take some work – there is no – convert button to push, but they are not that difficult once you start doing them.
Oh this is Ruby by the way – just noticed I wasn’t signed in as me
