To state the obvious: commercial yards are responding to a very different set of incentives. They are either meeting a quote, or being paid by the hour -- either way, they have a strong incentive to complete things well, but quickly. Leo is being paid by viewers and sponsors, who enjoy the content that painstaking labor produces. So he has succeeded in putting himself in an enviable position: he clearly enjoys doing very careful work, his clients are very happy to support his attention to detail, and he gets to keep the product of all this effort at the end. It's brilliant.
