...to do this. The climb data is the hardest to document by hand. You need to write down Zulu times starting and finishing each 2000 foot altitude block and also the OAT at the middle of each block. HOWEVER, you can get all of this data by downloading the Dynon data log after each flight. Just write down the Zulu time beginning the climb so that you can find it in the data log later. There is a lot of stuff recorded in the data log but if you are willing spend a little time at the computer after the flight, you can fly the tests with a minimum amount of distraction flying the airplane.
I believe Van's considers deciphering the data logs to be worthwhile experience since they have you download and archive them after each test card.
The same holds true for the speed boxes. And, if you have the autopilot, you can just dial in the courses in the Heading Mode and let the autopilot hold the altitude while you watch for traffic and enjoy the ride

. I think they intended the autopilot option for us old guys

. Just remember to jot down the Zulu time before starting each block so you can find the data in the log. Then get the data from the data log after the flight.
Of course, you have to do all the stalls and other air work, but it's pretty easy to record the needed data on your clip board after each of these manuevers.
I interpreted the Operating Limitations to mean that I had to finish the Flight Test cards before making the required statement in the aircraft log book no matter how many hours it takes. Otherwise, I did not feel that I could certify in the log book that "the aircraft is controllable throughout its normal range of speeds and throughout all maneuvers to be executed, has no hazardous operation characteristics or design features, and is safe for operation."
I was in no hurry to fly off the cards. I wanted to take my time with the new plane and I determined in advance that each of the 5 cards would take me more than 1 hour. Not being a test pilot either, I set goals for each flight that I could attain.
I found that flying the test cards gave me a very good indoctrination in flying this aircraft as just about every flight situation is addressed, at safe altitude. My test card data are not perfect, but I did them to the best of my ability, and I felt secure that I had done a good Phase 1 when I signed off the log book.
