Indoor sowing melons, cucumbers, squash
I noticed on a link I was sent that if I wanted a head start in sowing watermelon, cucumber or squash seeds, I should do it 4 weeks before transplanting time. Is there a reason it should be 4 weeks (or less) vs. 6 weeks?

Here is our germination chart for sowing selected vegetables indoors http://extension.umd.edu/hgic/starting-seeds-indoors
You can direct sow but if you want fruit earlier, sow indoors 3-4 weeks before last frost for Cucumber and squash. These plants grow quickly and can be difficult to transplant. Try to disturb the root system as little as possible.
