A/B Variants Not Showing Equally Despite 50%/50%

#1

Hi, guys:

I have two variants and they’re both set to show 50%. One is showing 6 visitors, the other is showing only one.

Shouldn’t it be 3 and 3?

#2

I expect that the 50% is calculated for each visitor rather than for overall.

So like flipping a coin six times, 5 and 1 is very doable but over time it will even out.
