Longer transmission time gives it more time, before repeated. Increasing the chance of a response?Go HERE it explains it easier than I can (FT8)
WSPR2 is different but still the same principle, a TX lasts 110.6 sec and send my calls, maidenhead locator power etc, repeated of course.
As it is 108 sec long, it can reach the other station better than the short 12.6 sec FT8, peaks and troughs of propagation.
a FT8 exchange can last 6 exchanges, can be cut to 5...
WSPR is just a sending of rx'ed signal to a central database via the program
You also have FT4 which is 4.48 secs long so is faster again but slightly less sensitive.
WSPR2 can decode down to -34db
FT8 can get to -26db
FT4 struggles at -20db although I once had a -22db report..
I might try one later
I'll be honest and say most of that has gone right over my head.
