SEMI: Ratio or Absolute?

According to View from Silicon Valley, on the one paw, the SEMI book-to-bill (B:B) ratio has leveled off to 0.93 in December. On the other, bookings are way down, to some multi-year low, and still going down. So the slope is leveling, but on the other other paw, the slope can level at any absolute level, and is not necessarily reflective of such.

By the way, according to one late, great Richard Feynman, on making calculus accessible:

The French curve is made so that at the lowest point on each curve, no matter how you turn it, the tangent is horizontal.

Apologies if this tangent wasn't humorous...
