Total Acids question ... expressed as Tartaric or Malic...??

[Sballe]

So, I know that a TA-kits usually (if not always) express the result as Tartaric Acid ... which then should be multiplied by 0,89 to get the 'proper' result for at cider, which is mainly malic acid...

Right now, I am in the process of balancing the acids in some carboys ... and came across this article discussing a good TA-balance in cider, and it said: " Most ciders fall between 0.5 to 0.7% TA. At The Beverage People we generally recommend a tighter target of 0.6 to 0.65% TA."

BUT, when talking about TA in cider -- would that normally be already converted to Malic acid ? Or should this number be multiplied by 0,89?? So when they say a target of 0.6-0.65 good ... would that actually mean I should aim for a reading of 0.675-0.73 ? (which multiplied by 0.89 equals 0.6-0.65)

Does my question make sense ?

Email and ask The Beverage People. They seem to be knowledgeable, and I find their articles are good value.
