MaxDiff RLH with 9 sets of 6 items each and each item shown 3 times

We ran a MaxDiff with 18 items.  We used 9 sets of 6 items each and with each item seen 3 times.  N=150.
The RLH is running from .17 to .58.  What should the minimum RLH be to for good respondents?
Thank you!

Thank you.  Based on the numbers I shared, is an RLH of .17 too low?
Probably, yes.  It's essentially the fit you'd expect from random responders (6 items/set you'd guess random data correctly 1/6 = 16.667% of the time).
