This means that ~61% of your test match was devoted to a discussion of this single variation. The result was that 2,111 (!!) games after that position ended in the same short draws with 20 or 21 moves each, because the two games below were repeated over and over:

These two games make ~53% of your test match, having been repeated more than thousand times each...

1) it was not mine test match
2) test author wrote that Rubka 3 book has been used for a tournament, so no wonder about those repeating openings.
