Correct, her natural lvl 18 casting rate cannot exceed:

R = 1/8 + 1/10 + 1/11 + 1/100 ≈ 0.3259   [spell/sec]

Further, with full 45% CDR, this cannot go over:

( 1 - 45% ) R = 0.55 R ≈ 0.5926   [spell/sec]

But if she had an innate up all the time it'd require a spell rate of at the very least:

r = 1/1.5 ≈ 0.6667   [spell/sec]

Thus R < r, a contradiction.
