Actually, I'd rather know your conditions and do the math.
What is it you need to do with your LED's?
VDD, LED Forward Voltage / Forward Current?
See if the theory works?

Because the voltages across the resistors are changed by the voltage drops that are controlled by the LED's.

I would just LOVE to haave proteus. I tried looking it up 1 time, seems it was in the triple digits, just a little much for me
That's what I thought too at first.
But they have a $250 "starter version" that gives you a 12F, 16F and an 18F.
Of course it comes with all the other logic chips, analog stuff and test instruments.

Even if it's not the exact chip you target, the "Family" is usually close enough to know your program has a chance.

Beware:
Once you get used to it ...
You probably will spend $1000 for the full PIC version.
