Talked to rob at cycle stop just a minute ago Bernie. He said that he'd be happy to explain why the pressure relief valve was placed at the well head and why it should be relocated downstream of the valve.

When you call, ask him how he likes his new F-350. It's a funny story. 1 (800) 652-0207

As a quick fix, install a cycle stop valve - http://www.cyclestopvalves.com/prod_csv125.html - and it will stop the pump from short cycling. It will vent water from the pressure relief so if the well is in a pump house, you're going to need to plumb that to drain outside.
I second this. A cycle stop valve is a Fantastic addition to any system. It will prevent the cycling. I have installed into several so far and they work very well.

Is the pump on a steel drop line?

I have no idea how big this property is and what size main but 5 hp is huge.
Sounds to me the pump is way oversized and the tank is either faulty, old or undersized. CV's are nice but not a cure-all.

Not if they're lifting 5-700 feet. Look at the pump curves.

I thought this is a submersible it is pushing and only feeding 4-5 residential heads per zone.

Perhaps Mr. Mod Mike was correct in moving this thread: things are getting complicated without any of us knowing what's going on with the well. My limited experience tells me the well was not done right and the zones prolly were too large. I'd still be getting a pump test by someone different than the installer.

The water level in the well is probably very low, but for an acre, even at 350 feet deep, a 5HP pump seems a bit much.

What are the pressure switch settings?

On the same zone on which the OP nozzled down by half GPM,
suppose he nozzles down by half one more time, bringing the zone gpm to 1/4 of the original gpm,
if: this broght the cycle to two minutes.....would this point more strongly toward an insufficent replentishment flow of water source?

(i have no idea what we are talking about I am just gambling/trying to learn)

If the pump is short cycling, he doesn't need to use less water, he needs to use more. It's short cycling because the pump is rebuilding pressure in the tank faster than the zone is depleting it. The way to solve that is to combine zones to increase flow, re-nozzle existing zones for increased flow or install a cycle stop. I suggested a cycle stop because I haven't seen the system so it's the only solution I can safely offer without knowing what we're dealing with.
