Yeah, I'm weak in mathematics. But I didn't count Asuka's wins on my own. The site you referred states "170" wins. Another site I saw states "163" wins. A couple of sites have already said that the streak has been passed. Asuka herself has tweeted referring a site which stated that "Asuka passes Goldberg's undefeated streak." So it's not about my "off" mathematics.
Also, the legitimate number is "155" which is already passed.
