22-23 what? Are you talking a specific tensionmeter reading? Spoke tension is generally quoted in kilograms force (kgf) or Newtons.
Different manufactures of rims have different limits of max tension. Theres an example table here:

Generally, I've always tried to go for about 100-120 Kpf for spoke tension (for anything other than non-drive side on a road hub). But it depends on spokes, rims etc.
When building wheels you have to pay attention to both average spoke tension and max/min tensions on some of the spokes that are a little more/less tensions than average.
