That's an interesting philosophy: 'don't mess with what works' --- Americans say: 'If it ain't broke, don't fix it.' Which is one of the main pillars of great ancient wisdom that ruined their automotive industries. The Japanese say: 'If it works well it's worth perfecting.'

They do that by leaving it well alone for daily work and life; then having a perfecting room or area that is entirely separate, that can't upset production. When the perfecting cycle has taken one well defined and measured step forward it is adopted into daily work. That can go on for ever, and does. Their bullet train was trialled at a very safe speed: and run at that speed for one year; while all problems were investigated and fixed. Then 5km hr was added to the speed for the next year, while the effects were carefully noted; problems were continuously remedied. That went on for many years without mishap and the bullet train gained an enviable reputation. It is how they lost their war, though, 50 to 60 years earlier, as they could not improve their airforce to keep pace with American ingenuity under pressure.

It is only recently that the spread of American financial irresponsibility led to lowering costly safety that a few incidents began to tarnish the bullet train's performance.

Hi Michael,

There are only minor changes, like trying harder to avoid showing the same
card twice in a row, not scheduling related cards on the same day, etc...

My philosophy there was also 'don't mess with what works' :-)

Cheers,

Is there any substantive change in the scheduling algorithm between 1.x and
2.x, or is 2.x more of a usability upgrade?  I'm perfectly content with 1.x
and have no desire to mess with what works right now, other than the
obvious lack of support for an old version.  But if there's a scheduler
change, that would change how I think about it all.
