I'd agree with that, which is why I said 'max'. But sometimes you have to creep over.
Another tip is; if you're using an agency - find out what CV presentation format they use. In a lot of instances, an agency will tailor what you submit anyway to fit their template. Contact details for instance, will be taken out. If this happens, you might have some agency bird taking out what to you, is an essential part of your CV before sending it on, possibly because the client is screaming for potential interviewees and she is harrassed. Ask the agency for an example of what they send on to an employer and tailor the body copy of your CV for that.
