C100: How to expose for canon c100 wideDR mode

Two questions:

1. Is view assist mode meant only for clog or is it meant to be used for wideDR mode as well?

2. I have read posts about how exposing for clog is different than other profiles due to the extra dynamic range. When using a waveform 32ish is actually middle grey and I get that. But do these rules apply to wideDR mode as well? Or do I shoot wide dr using the same waveform rules as a standard picture profile? How do I expose correctly for wideDR mode?
 
Wide DR expose as you normally would. I'm kinda new to the C100 so haven't figured out the c-log myself. With Wide DR I don't expose to the right like I would on my 5D when shooting RAW stills, instead I have my zebras set at 95 and just look for a good waveform while evaluating where my mids and highlights are. No idea if there is a better way, other than judgement.. lol.
 
It is better to little underexposure the middles with WDR, because the overexposure of middles can cause a desaturation on some parts of faces. I don't like this.
 
Thanks so much for all your feedback!

To be a little more clear on my original question, as I understand it, you are looking for a slightly different set of values on your waveform monitor when shooting c-log vs standard recording.

Here is an excerpt from: http://www.hingsberg.com/index.php/2013/01/canon-c-log-exposed-literally/

"For example 18% middle grey which is normally 50%IRE moves down to around 32-33%. 90%IRE (white) will appear on your waveform monitor at only 62-63%. It’s really important to use these new values (even if you don’t understand them) when setting your exposure in C-LOG mode since it will maximize the dynamic range your sensor is capable of and preserve as much of the scene information as possible."

So my question is, when using wide-DR mode, would I use the same values on my waveform as though I was shooting standard (no pic profile) video (i.e. 50% middle grey and highlights around 90%)...or would I use values similar to the c-log guidelines mentioned above (since c-log and wide-DR BOTH aim to preserve as much dynamic range as possible)...or does wide-DR mode require its own unique set of values?

Judging from the answers above it sounds as though I would use the same waveform values as I would for standard (no log or gamma) video recording; not the c-log values.

Am I correct on my understanding?
 
Where have yall got your zebras set then for wide dr? Incidentally, I still havent ventured into c-log yet becuase I still find it confusing, especially if you're shooting outdoors without a grey card. Guess I'll get there eventually..

Avian, thank you for taking the time to respond. I have actually watched this video series before -- but I must have forgotten the answer was in there. Thanks again for pointing me in the right direction.

So to sum it up: for most shooting situations in WDR I will try to hover around 70ish for whites/highlights and around 45 for middle grey.

I second this question: where do you set zebras for skins/highlights in WDR? And how about C-log?
