I can't say for sure one way or the other just yet as I haven't really thought about the actual design portion. Still trying to get everything done for this release so I can't make any promises either way. I think for now the best thing would be is if you have a moderate use board is set the default for a large number. Like I said this feature doesn't do much for a moderate useage forum except for the a user with a slow connection that visits often in that it would allow them to change it to a smaller setting for quicker loading.
