In this file "-94" and alike are not at the end of lines, as they were before. So no lines were excluded. You got 50% of 5 lines, so 2 lines (2.5 rounds to 2).

## Let's say that:
## the number of lines in your file is 200 (range=200);
## you want 30% of the lines in your file: percent=30.
## So we'll have that lim= 200 * 30 / 100 = 60.
