That is an awesome gadget Rainsey, please do keep us posted mate! Not to get you spending more money but it would be cool to see 2x cheapo mechanical temp guages zip tied along each hose reading the temps at each different pressure locations you test maybe? Once you've tested the outer bonnet pressure zones it would also show ambient temp wind incoming on the day of graphing data I'm thinking? Like Mythbusters I guess with their first 'control test' before all others :-)
