Error margins in the future too - wow! By a 'second type of data point' 
I meant a different coloured point which indicated data that had not 
been actually measured, but was a broad estimate based on periodic trends.

I was not suggesting that Kalzium use mathematically derived estimates 
for unknown data, but that it could use human-derived expectations for 
each unknown data point. For example, Kalzium might indicate 7.5 (or 
perhaps 7.0) as the predicted density for astatine. Sometimes unmeasured 
estimates are available on the web, or a chemist can make a predicted 
estimate. On the other hand, please disregard this notion if it is too 
messy or time consuming to place separate, visually distinct, points on 
the graph in this way.
