Huma reg tester necessary?

Looking to get a huma reg for fx wc mkiii 22 and tune for 23g nsa slugs. So, what are the experiences of adjusting regs for those who have humas? How accurate/inaccurate are the readings?
My thinking is that if the readings on the regs are accurate but off I could simply compare readings to my gun gauge and get an accurate plus or minus reading from the reg itself this not needing the reg tester.
