G'hamO, The upgrade strategy page is only helpful if you plan on 100% completion. There is no way for this series to be be net positive at 100%, even with a discount much higher than 50%. But with free cars and a 50% upgrade discount it maybe be possible to find an upgrade strategy that comes in under the 75% bonuses for both F-E series and the 300GC bonus net any sponsorships that must be bought.

The info  we need is what PR is necessary to win 4,5, and 6 sponsorships and what it costs to get those PRa.
