H&D Curves with 510-Pyro?

Generally speaking, it seems by eye my 510-Pyro 1:100 rotary times seem pretty good and seem reasonably decent with the SP-8x10 though I haven't processed too many sheets in the SP. At this point, 510 has become my general goto for the films I shoot, though I use Adox XT-3 for pushing still - especially with HP5 at 1600 in 35mm. It produces exactly the results I want so I'm gonna leave that alone and enjoy!

Anyways I spent some time working out H&D curves for various other developers (Xtol, XT-3, D23) and think I should perhaps do the same with 510. But I recall reading the stain can impact the results? This is for normal printing process (not any of the UV processes). Can I just use my X-Rite 301 and get expected results for normal printing? While I think I'm pretty close, it would be good to verify, especially with the SP-8x10 since that's a different process than I'm used to (compared to my rotary processing).

You will be fine. Even if your stain fades decades from now, you are unlikely to have the same printing paper available to make an identical print anyway.
