Yeah, I get that. Thing is, I don't know the MOFI model, i.e. what their staff's arrangement is and what they get paid. For sure it is different from everyone else, who basically comes on staff at a mastering studio and is either on salary or gets paid by the project. For many, even some with a 'name' in the audio world, the arrangement is like taking a chair at the hair salon - you get a % of what you bring in. No work, no pay.
To be fair, KG has been working with RVG tapes for over a decade now. And those are very good tapes, often needing close to no adjustment. He knows BN/RVG like the back of his right hand now, and can crank out BN pretty fast.
On the other hand, not knowing the model the MOFI guys work under, they apparently have the luxury of not being timesheet punchers. Having been in that situation in consulting agencies most of my life, and then having been liberated, I can say that you can do a very good job and learn how to do so with time discipline in the hourly model, but free from that, your time discipline breaks down, and you often find yourself spending a lot of time pondering, tinkering, experimenting and generally working around a project - but have, in the end, the ability to do an even better project.
As Einstein said - if I have 10 hours to solve a problem, I will spend 9 hours thinking about it, and 1 hour solving it. The same can be said about mastering, although I suspect there are diminishing returns involved.
And the flaw in Einstein's argument applied to my business, for example - and likely most mastering people - is that no one pays you for the first 9 hours.
