metrics are lacking - and how do I know If I'm ABCDE?

The interface is really poor. Why do we need to go elsewhere to read about races?  So I do…  I see this.

“A: 4.0 W/kg FTP or higher
B: 3.2 W/kg to 3.99 W/kg FTP
C: 2.5 W/kg to 3.19 W/kg FTP
D: Under 2.49 W/kg FTP”

My ftp i found is 171 at present. But where do I find  W/kg? 

I loaded up Zwift looked around and didn’t find much of value. It even says YOUR BEST RIDE and gives some stats  but  NOT THE DATE?   Is my best my first ride on zwift? or my previous to last ride? 

I then sent to STRAVA and looked for this  W/kg?power rating and never found it.  How do I know if I’m  A B C D ? 

to make matters worse - what is level? and how do you go up or down? I think I’m level 6 - so whats it mean?

also annoying. I can only discard or save and EXIT.  No save and stay in?  No discard and stay in?  

Watts per kilogram = Watts divided by weight

Example 200 watts divided 65kg = 3.07w/kg 

It should be next to your name in real time when riding in Zwift.

There is already a lot of suggestions about the discard or save.

so if my ftp is 171 watts? and I weigh 158lbs

171 watts  /  71.6  = 2.38? =  D  ? sounds right?

D sounds right.

There could be some C sandbaggers and maybe even B in the ride. Some people have ego issues.

Most of what you have been complaining about has been brought up MANY times and hopefully in the upcoming updates we will see some of them implemented.
