It has certainly improved my email game. Just put any word down, check its percentage strength, and from that it's possible to work out what the 'best' score is, although I know from doing the puzzles that there are sometimes words with higher scores that the system misses.
Once you know what the highest score is, you can often work out, from the tiles in your rack and the openings on the board, what the word has to be, even if it's one that isn't in your vocabulary.
One thing it does not take into account, though, is defensive tactics: the highest-scoring word might leave your opponent the chance of a bingo, a treble/treble combo, or something like that, while the lower score gives you a better chance of winning the game.

@mistertoad No, I'm saying that the reason CH disappeared from your list was that for the game for which you supplied a screenshot you were using the American dictionary, which leaves out several words familiar from the British English dictionary, including CH and ZO.

@thatguythere202 Well, I only play e-mail, and I find that, by hovering over the edge of the play button, as well as getting the rough colour code, I am given an exact percentage of the highest possible score (according to the lexulous bot/algorithm). From this I can calculate the points available for the highest score, and from that sometimes what letters need to go on what coloured squares to achieve it. It sometimes leads me to look for, and find, bingos that I missed. Of course, the highest scoring move isn't always the best in game-play, as you may want to defend, manage your rack, or set up a future move, but I enjoy working out what it is anyway.
As I'm more interested in puzzles, anagrams and word games than I am in competing, I find the new protocol suits me very well, but I can see how it might get in the way if you're interested in playing with a ticking clock.

@dan-mitchell
and sometimes - well, once so far - you can find a word that scores more than their 100% word, and that immediately gets upgraded to the new maximum strength.

@roymccoy opps sorry replied before I saw this

SCATtILY down to the Y scores 91

@mistertoad That looks like the American dictionary two-letter word list: no ZO

While I appreciate the new, expanded stats page, some of them are puzzling to me. For example, how can I have 11,000+ bingos, but only 3,000+ scores over 50? Do the latter exclude the bingo bonuses? Or is there a time cut-off in some of the stats and not in others (I have been playing since 2009)? Why is my top score listed as 715 when I have screen shots of a game where I scored over 730? And what is the cut-off point for the longest word and highest score 'tile' displays shown on the right of the new lay-out, as I am sure I have exceeded both in the near-recent past, and my highest-ever single-play score over the past decade or more is well over 200, not the 100 or so indicated here.

While you're here :), does the points per move average include moves in the endgame when I had a less than full rack? Finally, do you include only classic lexulous in other's stats, as the large-board version (I have only played a couple of times: not for me), with its regular four-figure scores, would surely inflate some of them?

I have a different problem with player statistics: some of mine seem to make no sense. How do I have 11,000+ bingos, but only 3,000+ scores over 50 points, for example. My top score ever is shown as 715, but I have a screenshot of a game where I scored 730+.
How are each of the stats calculated? Are there different time periods involved? The Longest word and Highest score displays in the right-hand column, for example, appear only to relate to recent matches - I have been playing regularly since 2009.

@linda-mcdonald Click on dictionary, and the two-letter words appear - or at east they do on my version
