The results were:

CW (by ear) -18db below the noise
QRSS (3 sec dots) -27db below the noise
QRSS(S) (60 sec dots) -31db below the noise
WOLF -40db below the noise
...

The above figures seem a bit strange to me :
QRSS at 60 sec/dot should be 13dB better than QRSS at 3 sec/dot. I won't
argue about 1..2 dB more or less, but a difference of 9dB (4dB vs 13dB)
seems hard to believe.
Recent tests (eg. the QSO between G3XDV and CT1DRP) have shown even between
3 sec/dot and 10 sec/dot there is a significant difference (from a bare 'T'
to a solid 'O') that is probably close to 4dB.

Also the 9dB between 'by ear' and 3 sec/dot seems rather conservative,
other tests (eg. those done by DK8KW) have shown a 15dB difference.

I'm not saying that WOLF is not superior to QRSS, but the above figures
seem not correct to me.
