Plenty of folks. You can use paper to find arrows with a bad spine, you can use paper to adjust the nock on an arrow to the stiffest spot(spine). You can paper tune if your range is limited to only 15-20yds (no walk-back or group tuning there). Does a person need to paper tune? Absolutely not. But paper tuning can be very useful and effective if you want it to be . The trouble with it, for some,is that it is not as easy to setup and do as group tuning or walk back tuning or bareshaft tuning and so on.
