# Description of the Health column in the help file

## Recommended Posts

In the help file it says about the health column that:

Health displays 0-5 bars that indicate the availability of the torrent using: this formula -

log2(Availability).

I.e. distributed copies being

1 = 1 bar,

2 = 2 bars ,

4 = 3 bars,

8 = 4 bars and

16 = 5 bars.

This is inaccurate for 2 reasons:

1. in the UI, Health displays 0-4 bars.

2. the formula that's currently used -if I got it right- is: log2(Availability)+1

because:

`1 = 1 bar  (log2(1)+1=0+1=1)2 = 2 bar  (log2(2)+1=1+1=2)4 = 3 bar  (log2(4)+1=2+1=3)8 = 4 bar  (log2(8)+1=3+1=4)`

PS. I use utorrent 3.2.3

A: availability is a 'real' number ie: N.nnn

B: "Health" is an integer (N) so WILL have rounding errors.

C: Does it really matter??

My post was NOT about Health being calculated having rounding errors.

It's only about the description of the Health column in the help file,

which is inaccurate on these 2 points: the 0-5 and the formula.

Yes but my comment is with regards to the mathematics that is also in your post.
