You need the two breaks to be on opposite sides of the stick (since if they are on the same side, one piece will be greater than 1/2, so the other pieces can't match its length).
But given that they are on opposite sides, you ALSO need them to be not so far apart that the central segment is >1/2.
I.e., wherever the left break is in the left half, the right break needs to be to the left of within the right half.
The Echo CRT trialists did an excellent job discovering that CRT given to people with only mechanical dyssynchrony, killed you progressively over time. In the same way that CRT for LBBB saved your life progressively over time.
In other words they showed that it was not a procedural complication problem (that happens soon after the implant) but a progressive result of the pacing itself.
They rarely get credit for this exquisite insight.
Tony Blair is (for once) right that the most efficient use of the limited vaccine supplies would be to give everyone (who wants it) one dose, and once that is all done, and more vaccine is available, go back for 2nd doses.
HOWEVER, much as I love to kick the government, I can see fully why they are NOT doing this.
If I was the head of my village in Outer Francisia, and I had only n vaccine doses for my n people, I would give them all 1 each. (If I had less, I would give to the most at-risk)
You could say that the ball "wants" to go lower if possible. But ultimately it is being dragged that way by gravity.
We can use the term "want" loosely, when describing inanimate objects:
"The heat in this oven wants to spread out evenly"
But we know it is only shorthand
The mistake that leads people to think that viruses and other creatures particularly want to spread, is that Darwin's principle is often quoted as "Survival of the fittest", and we often misunderstand that as "Survival of the fittest creature".
