Question About LMC Doubled Die Reverses?

i have been reluctant to search for the doubled die reverses, listed listed mostly in to 2000 - to present. I thought they would be too difficult to see, and probably as infrequent to find as the older wheat's, etc. I separated a couple hundred 2003, an began searching them. to my surprise, I found 5 in the first couple hundred coins. 4 of them I identified and the 5th I plan to sent into coppercoins for attribution. additionally (after several hundred coins 2003 - 2005) I have found probably 12 DD columns (reverse). several I can see that are too minor to list, and two that I believe are significant enough to send in for listing. so my question is - are these just so much more common to find that then older DD and RMP, or have I simply had a extraordinary run of luck. I am finding them to be much more readily findable and somewhat more fun to search for.(i am still reluctant to search as much for the wavy steps. I most cases they seem so obscure I have trouble seeing them even the the photos).
