Williams has clarified the official number of races in which it has participated ahead of what it states is its 750th grand prix in Monaco this weekend.
Given Williams' history that dates back to its first race in 1977, historians have often questioned the exact number of grands prix in which the team has either entered or in which it has competed.
For lucidity, Williams has deemed it necessary to finally lay to rest any disputes as it becomes only the third team in F1 history to participate in 750 grands prix behind Ferrari and McLaren.
Williams state: "The count begins from 1977 as this was when Williams Grand Prix Engineering began the manufacture of its own chassis.
"The team raced with one customer car for the 1977 season from the Spanish GP onwards, competing in 11 races that year.
"From then on, every race in the Formula One world championship has been included, excluding the races indicated below [in the table] - three races in 1977 have been discounted as the team failed to qualify.
"The two races in 1980 and 1981 were competed by Williams, but as they were subsequently demoted from the world championship, these have been removed from the count.
"Similarly, in 1982 Williams did not compete in the San Marino GP for political reasons. This too has not been included in the count.
"Every race since then that the team has had at least one car on the starting grid has been counted."
