The back-testing algorithm for NHL has been updated with the latest release (v6.3.6) of The Handicapper. The algorithm was modified, because the dataset The Handicapper uses does not include historical line information on NHL games, just information on who was playing with respective playing times.
Previously the algorithm projected the lines based on playing times, which in the end was not an optimal way of doing it, because the lines were allocated different weights when calculating skill levels for teams. With the changes made, the algorithm is now simply allocating equal weights to all skaters, which is not an optimal way either, but produces results which are better aligned with actual calculations made on game days.
