Heh, here's what happens with 5174:

Correlation coefficient r^2: 0.773428 < 0.9
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec
1 sec = inf usec

And so forth...
