Having just read it myself, I have to agree.
To avoid the pitfall of the power dropping off in most situations, let the rpms remain high as much as possible by delaying the upshift whenever possible, as long as you don't get too close to redline or engage the rev limiter would be how I'd try to do it as much as possible.
True, mileage may suffer somewhat but even there, probably still better than some other cars in this class.
