Pool Math Description Wording

[HeyEng]

On the web version of Pool Math, there is the following wording under the pH measurements:

pH calculations depend on TA and Borate. Results are approximate and can be off significantly for large pH changes. Changing your pH will also change your TA. Users should be very mindful of their CSI when their pH is at the top of bottom of the suggested ranges.

Can someone clarify the underlined portion? I would think it should say "...is at the top OR bottom.." because I can't really make sense of it any other way. I attached a screenshot for specificity.

Didn't I *just* mention this AM that I have OCD? I noticed a while ago and didn't pay much attention to it until this AM when I couldn't make sense of it. Besides, I come from a world that had a lot of numbers with odd ball tolerances such as 10.8 +1.3/-0.55 and "off scale high" or "off scale low", so it *could* have meant something else.

Remember, it's just a pool not rocket science

Besides, that was a test. Congrats, you passed!
