I think he means ".2 ppm resolution using the 25 ml sample size" vs. ".5 ppm resolution using the 10 ml sample size".

Yes that's right

Your numbers are pretty close, not bad for a first time.

Generally, all you need is one scoop of powder, just enough to turn the water red. It's also important to try to always do it the same way. That way changes are tracked and meaningful. However, I wouldn't waste time and reagents running the 25ml test. The 10ml test is generally good enough. I've never seen a situation where I need to know if my FC was 10.4 or 10.6...10.5 is good enough. Generally the same is true of CC: If it's over .5, you need to deal with it. .5 means .5 or less. IF you have a persistent problem you MAY want to run the 25ml test just for the CC reading (If it's really.2 not .5 that's good to know) but I think I've done it maybe twice in nearly 10 years.

For now, (in fact, forever) ignore the "acid demand" and "base demand" tests if they are included. For lots of technical, and non-technical reasons, they are a waste of time. Two less things to worry about!

by far the toughest test to learn to run is the CYA test. It's important to hold the vial with the black dot at your waist facing the sun. You CAN dump the fluid back into the squeeze bottle and try again to read it. In fact, you can do it several times without having to prepare a fresh sample. I ALWAYS do it twice, just that way, to confirm my first reading.
