Two readiness numbers, two different rules

Why the two numbers differ

Different products read different inputs, weigh them differently, and compare them against different windows. Numbers built that way are expected to land in different places. A gap between them is not a contradiction, and it does not mean something has gone wrong with either one.

Which one is right

We are not going to tell you which number to believe. We cannot see what the other product read, how it weighed it, or what it compared it against, so there is nothing here to settle the question with, and a preference dressed up as an answer would be worth less than saying so.

What our number is built from

What we can do is show our own working. Every input this score reads, the weight each one carries, and the window it is measured against are below, and they are the same numbers the rule ran with this morning.

• Heart-rate variability40%

  Read in ms. Above your own baseline reads as the better outcome.

• Resting heart rate25%

  Read in bpm. Below your own baseline reads as the better outcome.

• Sleep duration25%

  Read in min. Above your own baseline reads as the better outcome.

• Respiratory rate10%

  Read in breaths/min. Below your own baseline reads as the better outcome.

Once per wake day, as a morning snapshot. It does not move again during the day.

Your own trailing window, never a population average and never another member. A naturally low resting heart rate is not a permanent bonus here, because the comparison is with you.

What it read on your own day

To see what this score is actually reading on a given day, open that day and look at the ranked contributors: each input is named with the direction it moved and how much of the score it accounts for.
