Exercise Load in watch 6

No doubt samsung is doing good in measuring exercise, but exercise load feature is still missing, how much recovery time was required after a heavy exercise is still missing on the watch and many other features. Vo2 Max is not justifying the load. That's the extreem I reached depending upon the oxygen consumption. But how is it effecting is still not here. 

Will be great if you can add Exercise Load feature so I can know if I was doing my best, or I can push my limits.
