I don’t think you can draw too many conclusions about pace over the winter of 93/94.
In the way Senna was so outspoken and so committed, I think you can.
Wasn't it also a matter of Peugeot being more comitted to the program with bringing in more money to the team than Chrysler planned to do. Thus forcing McLaren to search for additional fundings should they opt for the Chryslers?
If I recall correctly, this was indeed the case. Yet there was sponsorship from Marlboro and Senna (allegedly) would have driven for free. To me those would have been no brainers.
Yet one could imagine Dennis not taking the gamble for Chrysler and taking the safe route for Peugeot, like Payr said. Dennis committed his complete organization on Honda, only to be dumped by Honda after just 5 seasons. I can imagine this being fresh on his mind once he decided to go for Peugeot.
