Question about Iterations in Factor Analysis

[Thomas Roel Moen]

Hello,

I'm working with a PCA factor analysis with varimax rotation and I'm
wondering why SPSS has a standard iterations of 25?
What are the consequences of increasing this to 100 or 250, if any? (Of
course, depending on if the iterations above 25 converge versus the ones
below 25)

Thanks for any feedback!
