don't they generally adjust before a horses next race?

I've seen horses when I have used the original beyer that have been adjusted at a later date when I have looked at the same horse for a different race. I wish I could cite an example here to further my point but can't at the moment. Maybe someone else can answer that, I'm not sure.

By the way, I think we've all questioned a figure here & there when handicapping, it's all part of the process. At times you can even use that to your advantage.

If the information was the actual time of the race or fractions or other factual info I could see your point.

The brisnet figures which are not adjusted had these figures for the horse:

111
86
85
83
92
82
89
64
75

Keep in mind that for the brisnets each point equals a length. So the brisnet's suggest that the horse improved by 19 lengths off its' career best or 30+ Beyer points. So anyone that thinks Beyer is fixing this needs to call out the brisnet computer as well.
