I have a model that was generated using ML .Net Model Builder. I am using the ForecastBySsa engine. I cannot manually recreate the same results. I can use the same settings for the fitting (as provided in the auto-generated console app), but the model predictions from my code using the same data produces different results. Is the Model Builder adding/adjusting optional parameters for the fitting? How can I discover the parameters used so I can rebuild the model without using Model Builder? This is true for even the simplest data set (see below).

for example here's my data:

Time    Data
1/1/2019 4:45   0.000135722
1/1/2019 5:00   0.001085629
1/1/2019 5:15   0.000406669
1/1/2019 5:30   -0.000677507
1/1/2019 5:45   0.00040678
1/1/2019 6:00   0.00067769
1/1/2019 6:15   -0.000270893
1/1/2019 6:30   -0.000812898
1/1/2019 6:45   0.000542373
1/1/2019 7:00   0.002032796

Prediction from Model Builder: 0.0007719097

Prediction from retrained model (using the same data and windowSize, seriesLength, horizon) 0.00051951635
