Thrift Savings Plan

[Snippy]

Sharing tidbits of my process, if interested. This URL is from October, but relevant for annual pre-forecasting(so I think). What was surprising to me, was that after I spent 6 months building a file of historical data for the four TSP indexes dating back to their respective starting points and aligning/filtering so I can compare current date/month to historical trends/dates, I see this URL showing a historical average rollup chart of my detail. Was very interesting to see after I invested time building my data, but, at least I now have another tool to assist in pre-forecasting.
I try to set up a future Jan-Dec file (my crystal ball) each December targeting go-in points from this detail to have a baseline for analysis. The concept has proved to be beneficial for me over the last four years. Note this URL is specific to C Fund.
