I think you have slightly misunderstood. We are trying to estimate the number of people that own a car using the TT's in career series. Most people run the TT's in career because they give you an extra gold cup and percentage towards completion. The first TT obviously gives the best results as all you need is the car. TT's later in a series can be dependent on you having other cars in the series and/or saving showcase discounts and not progressing the series. Remember, it's an estimate but does represent the minimum number of people that won the car, not the number still playing or the number that race in WTTT. These numbers also let us estimate how many people have completed 25%, 50% and 75% completion of series.

Additionally, the Exclusive Series TT's are a good way to estimate how many people have those cars fully upgraded.
