Dueling experience and level

Your dueling level in game is calculated like this - Your real level + Level from dueling experience.
For example, your real level is 10 and you got 500 exp from duels (+4 lvl) so your Dueling level is 10 + 4 = 14

sorry, i dont understand.

What does 47 + 1 Level mean?
If my dueling level is 1, then i'll get 47 xp from dueling?

Thanks

No I think it goes like this. When you get to 47 deuling xp you get to level one and so on and so on.

Ok, changed description of table columns and added additional info. How is it now?

Oh...i see

Thanks
