I re-did 2016 and there was not a significant change. I looked at the stocks for 2015 and added about three. I don't think it is worth it to redo it.
I think it would be more beneficial to look at this from another angle:
1) Tally up the results and,
2) Look at how a portfolio would be constructed - how long are stocks held, when are they sold (which is the same thing).
