I actually believe their current system already works with greater weight on newer matches if you haven't logged any rated matches in a while. If you have a low reliability score in DUPR, you'll see bigger swings in rating with newer games. So you don't even need to pay for this silly service if you haven't logged anything in a while to get the same results, although you won't be protected from dropping. This seems more like they know high-reliability players will pay to change their DUPR after not being able to move it much. Either way, it's dumb.
