Fun with Ligatures and Brevigraphs

[JoJo_Jost]

What I don't understand, or am I making a mistake in my thinking:

If I can translate large parts of a recipe book in shorthand back using the Voynich alphabet, why should Voynich be a hoax? 
Even if the result is not really Voynich in its original version because I use different ligatures and brevigraphs? But it is the same game...

 At least you can see that the Voynich alphabet can work as it is. Here's a quick and dirty version of the third line (because it's the longest) of the recipe...

pectoris ac pulmonum dolores succus expressus bibe superpone.

ps tmac   plinoy   tschy   empr   chus   dide   srp   oye

(and now i undestand why the spaces are not the end of a word)

pec = ps(s.b)
t=t
ris= m (s.b.) (rm
pstm

ac = ac

pl= pl' (pul)
mon = ino
y= um
= plinoy

Dolores = t

S = s 
u= ignored
ch=cc
us= y
= schy

ex = em (s.b.)
pr= pR 
essus = ccy
=empRchus

bibe = d = b also dide

Sr = super
pone = poye
= srpoye

And if I wrote it myself, I can recognize it easily.
