We have also tested at distances much greater than 20 feet without issue using 120 Ohm's of termination on each end of the BUS.
FYI a termination resistor of 100 ohms is outside of the spec. Teams using 120 ohms resistors should have no issues related to signal reflection.

From the getting started guide:
Total Cable Length
(maximum)
20 ft / 6.1m Tip: Start with this length of bulk cable and cut all
segments from it to ensure compliance.
Termination Resistance 100 At each end of the network.
Just quoting specs.
