hand dispersion

[SeanSkill]

Not being a math guy I was wondering if I could get some help on this? I notice in my poker tracker database that there seems to be quite a difference in the number of times i have been delt each hand. I only have 21,000 hands so I am sure that my sample size is not large enough for the numbers to converge, but at what point might i expect this to happen. Also for every suited hand I should expect how many unsuited?
