How Personal Points and Team Points are distributed

If you are not on a team you cannot take the personal points accumulated so far to the team that you may decide to join
After joining your first team, only the points generated while on that team, count towards that teams total points accumulated
If you leave that team, the point’s accumulated while on that team, stay with that team
If you then join another team, only the points generated while on this new team counts towards that teams total points accumulated and will stay with them if you leave
And so on and so on
However any points you have in your personal profile since you joined will always increase and stay with you
Your total personal points score will increase irrespective of which team you join or leave
If you look at the very bottom of your personal stats page it will list the teams you have joined and the points credited to each team you have been a member of

I hope this helps to explain how points are distributed
