Since your Gold came from only foils, it was probably reasonably clean to start with and would have settled pretty well. Assuming you did a few washes, you probably have above 98% purity there very easily, probably more like 99.5% +
The washing that butcher describes becomes much more important when you recover Gold from 'dirtier' sources, where you have more base metals in the solution with the Gold.
Well done though, it is always nice to see someone just follow the process and get the result, it is astounding the number of people who do it for the first time, but decide to change the process along the way ?!?!
