We present a conjecture that expresses the number of Wedderburn components of Q_p G of a given \u201ctype\u201d as an alternating sum of those numbers for blocks associated with b on p-local subgroups. We prove that this conjecture is equivalent to a refinement of Alperin\u2019s weight conjecture due to Turull and that it holds for various classes of blocks.
