comment How to make a flowchart?
Although Mathematica's graphics functions should be able to draw all this, and the graph drawing routines have quite some flexibility, I don't think Mathematica is a good tool for this. There are several (even free) programs that would be a better choice.

comment Fitting bivariate data using FindFit
Are you sure about the {x, y} argument? You get the above warning only when you use {x}. Using the function as above yields another message: FindFit::fitc: Number of coordinates (1) is not equal to the number of variables (2). >>

comment Why is Random faster than RandomReal?
If you need the random numbers one at a time, can't you just generate a few million of them in one call (RandomReal[{0, 1}, {10^8}]) and index this list during your iterative process?
