That is an awesome ratio! And you are right, sometimes the older fandom stuff gets a good 10% kudo/hit ratio, while my Teen Wolf stuff is down around 5% kudo/hit ratio or lower, although they have the hits to get a lot of kudos.

Right now some of my Losers stuff I am just posting are at almost 20% kudo/hit ratio, which is astounding!

Your 50% is clearly tremendous!
