Best close-up of universe's most massive star reveals it might be smaller than thought

"star may be closer to 170 to 230 times that of the sun — which still qualifies it as the most massive known star. "

I know wiki is not the best source for information, but it says this:

Westerhout 49-2 (in Westerhout 49)25036,20018.246 (J band)35,500SpectroscopySIMBAD[5][6]
BAT99-98 (in Tarantula Nebula of LMC)226165,00013.3745,000SpectroscopySIMBAD[7][8]

Second column is mass. According to this, at least two other stars we know of are more massive than the one in the article if the new measurements are correct and depending on the actual mass (170 SOL or 230 SOL).
