I've seen a few posts relating to:

9500I (8500 X50) has no off axis detection
STI 38.8 detection is non existent.
(Various things about the RX65 and 995)
V1 sucks at 35.5 off axis

And that hopefully in a new software release these issues will be fixed. This leads me to believe it is more DSP than hardware. Is there any way to get a free (minus shipping) upgrade for fixes to these deficiencies?

Or am a wrong and the issues are hardware which means wait for a new model down the road that may or may not work better / have a different set of issues.

PS for $300/$400 you would think they would not have these deficiencies.
