The third level of the Statistics advancement shows how many of an alloy or crafted item are needed to get all visible techs. This does not include how many are needed to craft the items. It would be nice if the stats included this information.

For example, as it works now, if you've bought all the techs that require copper the stats screen shows that you don't need any more copper bars. This isn't really true though if you still need copper wire. Say you need 40 more copper at 4 copper bars apiece. It would be nice if the 160 bars needed were included in the copper line of the statistics.
