NCL Pearl Points / Rating low

[id10t]

Just got off the NCL Pearl and had my worst point rating and on board credit at the end to date.  I have played in NCL ships many times and have earned Pearl status from table games before this cruise play less with less money.

I am aware that table games do not give much points, and that points and status are based on play time and money bet.

 

This eleven day cruse I spent over 30 hours on the tables and average bet was around $50 a roll on craps, $50 a spin on Roulette, and $25 a hand of black jack. 

 

I did not even break half way in points to pearl to keep my status.

 

TLDR: Did NCL change the way they evaluate play or was I just luck the last few cruises with great pit bosses?
