I would disagree, that all your findings support your proposed steps towards fixing.
>From my experience xtimer indeed becomes increasingly unrelieable below 30 microseconds. I think the information for users should include microseconds instead of ticks, since it is more intuitive.

Of course current usage of XTIMER_BACKOFF must be reviewed, whether it is used to compare against us or ticks then.
So from my point of view it is not a problem of documentation, but of proper casting. I'd even prefer if this value of 30us is reviewed properly, to determine a more exact bound.
