That makes two of us I guess. What is the HTP histogram is a conversion of? Is it not a histogram of ISO 100 (equivelent) plus the HTP curve.
The histogram you showed me looks like the histogram of the image that the converter would create; not the RAW.
The histogram of the RAW image would be the same for both, if the absolute exposure was the same (same light, Av, and Tv).
ISO 50 and 100 aren't available when using HTP. Are you saying that 30 sec @ f/11 would have the same exposure at ISO 50, 100 and 200/HTP? I definitely don't understand.
They all have the same RAW histogram; the RAW metadata simply notes that they have different RAW values intended to be white in a conversion, but you can always override that in a converter.
