Same issue here… Some information for you.
In this case the max. execution time for the blog software is: 2 seconds.
The time needed to correct 10 rows in the data base: 0.00461411476135 seconds
Select an increment: <= 9 (The increment should be smaller than this value)
Number of rows in the data base table wp_podpress_statcounts: 803
Number of rows which need be processed: 634
the increment starts at 10 and every time you run it it counts down by 1. Then if you let it try and run with any of the values it just hangs. Have tried in firefox, chrome, and IE and running wordpress 3.5.1
