We will study the centered Hardy-Littlewood maximal operator acting on positive linear combinations of Dirac deltas. We will use this to obtain improvements in both the lower and upper bounds or the best constant C in the L 1 → weak L1 inequality for this operator. In fact we will show that 11+√61/12 = 1.5675208... ≤ C ≤ 5/3 = 1.66....
