Which historical EPS data best correlates with EPS Estimates in Earnings

I'm a new subscriber and I'm really enjoying all of the great research and ideas. 

I'm hoping someone can point me in the right direction on something that seems very basic is eluding me.

I'm trying to put together three year projections of EPS growth using historical data for the previous four quarters and Earnings Estimates for subsequent years. When I add the EPS Surprise Actual data for the four previous quarters on the bar chart in Earnings, the total is far different than the ttm EPS data in the Key Data  financials. 

What information should I use for ttm EPS in conjunction with the Earnings Estimates that would be most accurate (or calculated similarly)? The bar chart "Actual" data or the key data financials data? To compound my confusion, in the financials there is also a Normalized eps which is also not close to the "Actual" figures.Three different numbers for ttm EPS and none of them very close to one another.

I've checked this on four or five companies and the information does not correlate. Anyone have ideas on which historical EPS data best correlates with Seeking Alpha's Earnings Estimates for the purposes of caculating EPS growth and Net Margin growth?

Thanks in advance for any help.
