Yes, your sample size is way too small. However, I do believe there is a signifigant difference between the $11s and $22s. Maybe from someone playing the $55s+ the two won't seem much different, but from down here it is noticable to a degree, to what degree I don't know or else I'd be doing alot better there. But anyway, none of this matters to you, because your sample size is too small.
