Hi Zajda,
The slope is definately tooo slow for really low EC but:
Try to move more gently from one side to another - You start by pushing Your knees first and then Your body follows aech time You initiate Your turn... In my opinion it would be much better to lean forward or backward and wait till the board reacts for the turn. Better than forcing the board to turn as You do.
And the other thing I see is that after the turn, You stand copletely straight for a while, than You start the next turn. You should start the next turn just when the previous hasn't really ended, but You are finishing it...
Anyway - It is really nice, but You can see that You make one turn, than You are going straight , than next turn, than straight once more etc. There is always this break between the turns. The real fun starts when the next turn seems to be continuation of the previous
Nice progress BTW can be seen through the three videos You showed us
I'm looking forward to the next videos.
