I have a question regarding keyword relationship within an adgroup.
Say I have an adgroup that is at 10% ctr and I have a new keyword in another adgroup costing me say 50cents, that adgroup is new and its ctr is pretty low, so the keyword cpc is probably at high side.
If I move the keyword to the 10% ctr adgroup over time will the adgroup 10% ctr improve the price of my new keyword?
I'd say no, it will not improve the price, because real CPC is based on Quality Score, and QS is calculated at keyword level.
AdGroups CTR is just counted as an average value - clicks from all your keywords divided by impressions from all your keywords.
There is however one thing that matters here - your account history. If you would for example operate on two or more AdWords accounts and had a successful campaign for keyword1 in the past it is better to start new campaign or adgroup on the same account, because AdWords system will then have more data to calculate things and generally speaking you should pay less for better position.

afaik keyword history retains at account level, so you can move your keywords around.
I did not understand your second question. do you mean that you have same keyword in more than one adgroup? if yes you should be aware that such adgroups will compete with each other, and you wont manage to get all your ads triggered same time. if you want to advertise two brands with same keyword then you need another AdWords account.
cheers,
Zaan.
There is nothing inherently wrong with using the same keyword in more than one adgroup. I do it in certain situations. I realize that only one "brand" will show for a given search, but after time I can assess which brand converts better.
If you do this, be sure to bid roughly the same amount in each adgroup for the keyword being used more than once.

As far as what the quality score ultimately resolves to - it appears to be some computation based on the relationship between the ad and the keyword and the landing page. It's understood by few and even fewer will talk about it ;)
Based on how it always flagged the same keywords regardless of landing page, often for inclusion of a preposition, I don't believe it has much validity as a true indicator of your "ad quality".
