Plasma Table - all cuts have tabs leftover but why ?

All jobs have tabs leftover. I use a LEAD 1515 with an powermax 45XP. I have dialed the 45XP recommended settings. (pierce height, cut height, speed, Amps...)

Below there is an example of my code, when I run this, tabs are left over. Not sure what I am doing wrong. My guts tell me it's between pierce height position and the X/Y move. Maybe I should give more pierce delay and slow the move from pierce height to cut height. (here it's F700) Any incentives ?

Thanks Peter. What I meant is that there were some bits of metal that weren't cut off the part.

And my intuition was correct. When dialing the Hypertherm Pierce delay of 0.2 s , I had tabs leftover which means the piece wasn't entirely cut.
Now, I have doubled the recommended amount and now it cuts around my piece without any problems.

Si if one experience tabs it maybe the pierce delay that is too short. Nothing less nothing more.

Thanks.
