I've only watched Toradora twice, but then I rarely rewatch things, and if I do it's usually only once. The only things I've rewatched to this day are Nichijou and Toradora. Fitting since they're my two favorite anime. Also kinda in the middle of rewatching K-ON!, but I'm taking my time on that one.
Let's see, I watched it for the first time in 2010, immediately watched it again, watched it a third time after reading the LNs, did one of those December rewatches a certain notorious web site likes to do yearly, and most recently watched it again with my little brother (who loved it. Oddly enough he was the one who found it and started watching it and I offered to join him a little later).
So yeah unless I missed something I counted correctly!
