I suck, I mean really suck!

So after 6 weeks of mostly zone 2 workouts 1-2 hours i did a new ramptest today. Finally an small increase from 183 wattt to 188 watt. It gives me 2.94 w/kg.

After i read some in a few polarized threads i want to try out a 3 week block and see how it goes for me. Does this seems about right way to do it?
