Matthias already landed a similar patch, see:
https://lore.kernel.org/r/20201111120334.1.Ifc04ea235c3c370e3b21ec3b4d5dead83cc403b4@changeid
I guess the question is whether 50 is better or 250 is better. Is this just a finger in the wind estimate or do you have data showing that 50 is better than 250?
