Confirmation that spaces are really spaces

[MarcoP]

This suggests that the spaces in the Voynich are not random. 

Hi quimqu, I don't remember ever seeing anyone suggest that Voynich spaces are random.
The problem is the opposite, as pointed out by You are not allowed to view links. Register or Login to view.:

Do spaces ever convey any information that could be required for interpreting the text, or are they wholly predictable?

Patrick also found that pairs that are hard to predict (i.e. can appear both inside words and across word breaks) also have a higher chance of being separated by an uncertain space
e.g. r_a: 631 apart, 573 together, 248 (17%) ambiguous

it’s likely no coincidence that the glyph pairs with the highest incidences of unexpected behavior also tend to have relatively high proportions of ambiguous word breaks represented in the Zandbergen transcription, i.e., what I call “comma breaks,”
