The correct PSI on new pump

Am I missing the link in pool school or somewhere? I can't find what good PSI would be for the pool pump. I have a 2hp, 2speed Hayward pump. 24ft AGP. (Yes, I already know, it is oversized.) Filter is cartridge, size 150. (I will make my sig soon, sorry)

When running on low, it is 4psi. When I add the solar bear panel, which is only 6ft away, on ground lvl, it goes to 5-6 psi. When I turn it to high speed, and solar off ofcourse, it is at 18psi. (I was told to only do the hi speed mostly for vacuuming. Do these numbers sound about right? There is a huge jump in psi on hi speed, but it is moving ALOT more water. A friend told me the 18psi is way too hi, so I thought I would ask here. thx.
 
The PSI values sound pretty reasonable for your setup and 18 PSI is not too high for a 2 HP pump on an AG pool with solar.
 
My baseline is about 15psi for my 2hp pump on high. It gradually gets up to 18psi, once it's close to 18 it's not long before it hits around 20 and then it's back-washing time. I'm sure there are plenty of variables that might make a difference. I believe low for mine is around 4psi too. In most cases 15-18 is normal for me.

Just noticed, your setup is different than mine. I have a sand filter and a gas heater. I'm sure the type of filter and plumbing could result in a difference in pressure.
