Tests results, look good but am confused and need clarification.

Did my water tests today with a new master kit, didn't get a GH and KH test as my lfs didn't have it. Here's the results I got. What I'm confused about is the ph test and the high range ph test. The regular ph test gave me a 7.6 and the high range gave me a reading if 7.4 I believe. So my question is which one do I follow?

The trick here is the regular ph test jumps from 7.2 to 7.6. So, a 'blue' reading can be anything from 7.3 on up. The high range low limit is 7.4. So, anything 7.4 on down will read the same 7.4 color. So, if you see a blue result on the regular ph and light tan result (7.4) on the high test, your ph is in the 7.3-7.4 range. Hope this makes sense!
