<p>In my mind, the prose of the sequels were so unlike Clarke when I read them as a teen that it created a long stint of aversion towards spending time on anything with co-authors. I owe Rendezvous a lot though; had I not discovered that book as a kid, there's little chance I'd be reading recreationally today.</p>

<p>The median US hospital is also a nonprofit; indeed, more than half are. I fail to see how focusing on this opaque median measure tells us anything meaningful.<p>Care to speculate on the trends I pointed out? I simply don't see how compensation for doctors is the problem.</p>

<p>Appreciate the perspective.<p>> <i>A not small number of the rural docs are foreign born and trained and they essentially work this crappy jobs until they have permanent residency and then they move to more desirable markets.</i><p>Not sure that I follow how "rural" necessarily begets "crappy" though. Is the working quality of life somehow that much worse, or is it the relative social isolation and/or lack of recreational options while off duty, or is it really just a case of urbanite out of their accustomed habitat?</p>

I'm curious what conditions merit a "match".<p>Aren't a lot of these shortages scattered around rural areas where young doctors really don't want to move to? I understand from a buddy who is currently in med school that there are all sorts of incentive carrots being deployed to attract doctors to these underserved communities.<p>[1] <a href="https://www.nrmp.org/wp-content/uploads/2025/05/Main_Match_Results_and_Data_20250529_FINAL.pdf#page=13" rel="nofollow">https://www.nrmp.org/wp-content/uploads/2025/05/Main_Match_R...</a></p>

<p>> <i>accuracy is a mix of both granularity and divergence</i><p>I respectfully disagree.<p>In context, "granularity" is nothing more than a resolution constraint on reported timestamps. Its inclusion adjacent to the specified "divergence from UTC" is a function of market manipulation surveillance objectives as discussed in preamble item (2), and really doesn't have anything to do with accuracy proper.</p>
