I didn't try to create your large file, but hopefully can can adapt this modified array formula:
You can probably get away without the double minus. I'm just used to being safe rather than sorry.
The "center" criteria is first as you had it, then the test if the K column is >0 and it's added to the P column. With this data, the sum is 2090.
