a pdf periodical for real hams and youngsters to become, will in next issue due Sept 1, publish a trainer I designed, that is in my opinion a lot better than LCWO words chapter. It repeats words at random that you did not copy the first presentation immediately.
Right now I am still on top in the yearly contest of the Veron at 71 wpm, but Jos PA1ZP is on my heels.
Jos PA1ZP: LCWO is nice, but a few remarks:
a) you can hardly measure progress because the max obtainable number of points in a "25 Words" load is plus or minus 30% of the average load.
b) you can only compare with your own results, not with others, because
b.1 the results are language dependent (German has at the average longer words, especially when o u a umlaut are simplified to oe ue ae;
b.2 fixed or variable speed is used, and
b.3 dependent on repetitions used or not
So I designed my own software,
The Ladderwedstrijd competition at hamfest DVDRA is comparable from year to year because at each presented speed the word length is fixed.
