How to display predicted data for a lead window size superior to 1 in Encog time series

[yokotsumo]

I am new to encog and try to fit the examples to my needs. I am using the SunSpotTimeseries in Java.

By default, the lagWindowSize is 3 and the leadWindowSize is 1. I do not worry about the lagWindowSize at the moment.
I just want to increase the leadWindowSize to 2 or more. For a value of 1, I understand that you get the predicted value through the 'predicted' variable (easy...).
My problem is I do not really see how to get the other predicted values if the leadWindowSize is superior to 1. I tried to see what was in the 'output' variable without that much success.
Thanks in advance
