We are working on lowering that number :)
It is quite a conservative estimate, we didn't want to claim something our PoC couldn't deliver. Also, it is with minimal attack runtime, as in, after you have those signatures and timings it takes a few minutes to get the private key. There is a trade-off where you can get around some of the noise and thus need less signatures if you just throw more computation resources at it.
