Simultaneous loops using PWM Bit-Bang

hi guys know there must easier way new code.

below code pwm using bit-banging pulse width modulation. reason went route because need add pulse @ end of each loop. there way run both loops simultaneously when run seem run 1 output signal @ time.

code: [select]

void setup()
{
  pinmode(13, output);
  pinmode(12, output);
}
 
void loop() {

look in ide @ example sketches loops , arrays sketches , learn that. blink without delay , learn that. @ point can shorten , merge variably blinking leds.
perhaps won't need array if counter , formula can generate pulse widths.
