Happens to me a lot too,
I believe its just badluck, but sometimes i doubt about what i believe.
maybe you will eventually hit it with higher balance, maybe we just have to try a little more
I never had a realistic target ever,
once i made 500 doge to 55k doge, 2million doge was my target
and one .00003ltc to .1ltc 1ltc was my target
and once .2 eth to 5.5 eth 800eth was my target
busted all in the end because my targets were too high.
