This constant factor may be large due to velvet fork security assumptions (m needs to be adjusted to account for this fact). Hence, this may make our implementation for velvet forks inefficient. In fact, the exact constants are not even known theoretically, only asymptotically. I suggest we are a bit more conservative on this claim.
