Got it. My point is I would not have an application to use the top 1/3 of the range, to 6000. If the 0-4000 was spread over the same area, as the 0-6000, that would make the gradiations on guage 1/3 easier to read. Also a guage with a lower top end would have a narrower tolerance range. This is not to berate your SPG. You asked if it was to small. If you can read it, then it is not to small. The key is if your tank fills are to 3500 then a spg only needs to show you that range. The most important part is the bottom 500. Harrold Buchannon, a DM on the Atlantis would say "You must return to the boat with no less than 327 psi". I had a scuba pro guage that went to 4000 then. I did my best to return to the boat with 328psi, sometimes more. Now I have a guage that reads to 5000 and found that the 328 is harder to find, but then again so is Harrold.
