Highest vacuum in the highest gear possible? Keep a constant vacuum up hill? Are you only concerned with drops in pressure? What about shift points in an automatic?

I use a vacuum gauge tapped into the distributor vacuum advance line.
It reads zero vacuum at idle, slowly rising with gentle throttle opening up to 95kph or so, then falls again as the throttle is opened further.
I'm not sure that this is a better indication of economical driving than the "normal" connection but it works well for me. I drive to maintain the highest reading in top gear that the terrain allows.
Of coures this only works on older models that have vacuum advance.
