It’s more similar to PAC Sim, which you could try on a variety of PCs, if you’d like to time those numbers.
However, if you’re worried about startup time of charts, I’d recommend using a different method. For those charts that must start immediately, add a loop at the top of the chart that waits for a flag to exit the loop (don’t forget your short delay, of course). Then, in your powerup chart you’ll start the chart right away. That chart will hang out in the loop until you throw the “Go” flag.
BTW, you implied in another post about how a loop without a delay will suck up ALL the machine’s time – not true, it’ll just squander that chart’s turn when you’re better off adding a delay to give the other pieces running a bigger slice of the overall pie. Page 4 of form 1776 gets into this concept.
