Tax refund and distribution

[KSL]

I'm confused on how the process works on Tax refunds and bankruptcy. My trustee said that if their portion of my refund is $1000.00 or more they would take it and turn my case into an asset case. This seems black and white. But I've read on the internet that if a trustee doesn't think it is worth their time to distribute the money they won't take it even if it is a $1000.00 or more. Is there a gray area here? What if their portion of my tax refund is $1050.00. Do you suppose the trustee would bother with trying to distribute $1050.00 to at least 25-30 creditors?

What is the determining factor for trustees on this matter?

i think to some extent it is how much he gets and if he thinks it is worth his time. I don't think (based on other threads I've read) that all creditors would share in the 1050, but I may be wrong.
