I've also been wary of the number of crossbows in that list.
Although I don't have evidence to support it, other than the inventories I've seen (in previous threads here and elsewhere) quoted for arquebus in Venice by this time, I would tend towards arquebus with the pike and not that many (1:7 max) at that. This was the Venetian's big experiment at 'modern pike warfare' using 'citizen pikemen' (rather than Swiss / German mercenaries) so I'm guessing they followed the Swiss / Landsknecht model of 1:10 shot to pike. After it failed, thinking Italian pikemen unlucky (Oman), they went back to hiring mercenaries to fulfil that role.
The French (their 3000 Gascons at Agnadello), on the other hand, definitely fielded crossbows and didn't abandon it until much later (possibly as late as 1525).
