Here's what I got done this month.
15mm Macedonians (commission): 32 phalangites, 2 charioteers, 12 cavalrymen (no mounts)
15mm Carthagininans (commission): 24 Greek hoplites, 24 Libyan spearmen
15mm Carthaginians (for me): 8 Greek hoplites
28mm Napoleonic French (for me): 2 fusiliers
15mm Napoleonic Austrians (for me): 64 infantrymen
1:1200 Napoleonic Naval: 1 frigate
So all told I painted 166 15mm figures and 2 28mm figures for a total of 257 SPPs. I don't know how I would count the frigate in terms of SPPs, but it took about 60 times as long as a basic 15mm figure.
