Some max turbo boosting frequency may cause XCPM: P-state table mismatch (error:0x4)

Hi,
With your help for the frequency vector (Thanks again!), I got my power management working under stock Turbo boosting mode. Now I am trying to raise turbo boosting frequency above stock. If I raise the Turbo boosting frequency from 4400(stock) to 4500 or 4700, I got

2014-12-19 1:01:35.000 PM kernel[0]: XCPM: P-state table mismatch (error:0x4)
2014-12-19 1:01:35.000 PM kernel[0]: X86PlatformShim::sendPStates - pmCPUControl (SETPSTATETABLE) returned 0x4
2014-12-19 1:01:35.000 PM kernel[0]: X86PlatformShim::start - Failed to send PStates

However, if I raise frequency to 4600, the pstates error is gone.
I noticed if I ran
ssdtPRGen.sh -turbo 4500
...
Number of Turbo States: 6 (4100-4500 MHz)
...

ssdtPRGen.sh
...
Number of Turbo States: 4 (4100-4400 MHz)
...

As you noticed, there is extra states created for 4500, 4700
in the master branch line 3939,

let turboStates=$(printf "%.f" $(echo "scale=1;((($maxTurboFrequency - $frequency) / $gBusFrequency)+0.5)" | bc))

Can you please verify the latest update because this is what I get when I run:

./ssdtPRGen.sh -p i7-4790K -turbo 4500

Number of Turbo States: 5 (4100-4500 MHz)
Number of P-States: 38 (800-4500 MHz)

Yes. The last update works. Thank you!!!
