mrbasketball,
IND spikes happen for a number of reasons. That particular stat is most useful in context of the rest of the data in your network graph (Ctrl+Shift+N while playing). If this happens often enough, can you reproduce it in, say, the training range? Maybe in 6v6 custom games with all bots? If so, get a screenshot of your netgraph right after a spike happens and the freezeup occurs. If you can upload that on a site like imgur/tinypic and link us to the picture, we’ll be happy to check it all out.
You won’t be able to post the full link with dots because you’re new to these forums, so just replace dots/slashes with {dot} or {slash} for now.
