crazy pipe diameter changes at POC

My pipe coming into the house is 1", which is then connected to a 5/8" meter, which then goes to a 3/4" copper pipe for distribution throughout my house. Since I have to connect right after the meter, I will have to tap into that 3/4" pipe. Now, the Hunter valves are 1", which means I will need to go from my 3/4" pipe to a 1" manifold. Is this going to cause problem? It's going to be all connected up like this:

1" -> 5/8" -> 3/4" -> 1"

Seems a bit weird to me. My water pressure is somewhere between 85-95 psi, so maybe this isn't a huge issue. Should I just connect it up and hope it works out? Or do I need to make some changes at my POC?

Not a problem. If you were watering acres of lawn, you'd replace the meter with a one inch, and maybe use inch-and-a-quarter for a longer indoor run of copper.
