PAL counter AVG don't match Perfmon AVG

I have a question about the values I am getting from the PAL Tool. I am using it to monitor sql server and when I look at the report it generates my avg lazy writes/sec are up over 100, but when I just few the perfmon log the avg is 17.  Which one is right?  Why is there a difference?  Anyone else seeing this differences in counter values?

Lee and I handled this offline. He started becoming much more accurate when he ran the PAL tool on a 64-bit version of Windows instead of a 32-bit version of Windows. I'm not sure why that would change anything other than the amount of memory that can be accessed, but it worked.
