There were a couple days of really big (number of words) puzzles, and unfortunately a lot of that tends to be grind-it-out stuff like adding various prefixes and/or suffixes. After a while, that can feel a bit boring (husband calls those bookkeeping puzzles... always have to check to be sure we've tried all variations of words). There was one the other day that was really tough for us due to the combination of letters, and on more than one day we couldn't find the final words using either of our programs. Then yesterday or the day before, I got queen bee by myself before finishing my first cup of coffee, and in comparing our lists today we were able to get queen bee without having to run our programs. The experience certainly differs from day to day or set of letters to set of letters! At least I got to try "yabba dabba doo" a week or so ago. I know, it has spaces. I still tried it. There have been a couple compound words recently that didn't appear in the puzzle that seemed as though they should given the random stuff they often include.
