If you stick with the program your rank will continue to increase over time, we are shifting to display the full fractions of boosts (under 1) but currently this is not supported by our display system. You may see 22 or 33 or 11 but it actually could be 22.2 or 33.1 or 11.5, does that make sense? I know it is a little confusing that is why we are updating everything this week to support and display the full Shadow Rank you have.
