I just found a puzzling discrepancy between VL results from two different computers running the same VL software. Has any one else seen this?

Friday I downloaded the latest weekly data set from VL onto my desktop. I calculated the PEG-13 list in preparation for trading on Monday.

For grins I just download the same weekly data onto my laptop and calculated the PEG-13 list again. Two of the top ten were not the same!

I verified the software is the same. I also verified the filter and user formulae: they are identical. I can think of only two possible causes for the difference:

1) VL updated the data between Friday afternoon and Sunday night,

2) the processors in the machines are different (Pentium II vs. Celeron)

The list generated by my PII using Friday's data is identical to that published on the TMF site. The list generated by my laptop is:


Any insights?
