Here's an estimated look for the amount of times (FRC "2015" Suggested) racing classes could be held with 52 (Thursday) weeks a year.
- • 4 - Mixed GT IROC
• 4 - Scalextric GT Challenge IROC (alternating)
• 8 - Restricted GT
• 8 - Historic Saloon
• 4 - Vintage Sports
• 4 - Vintage Sports IROC (alternating)
• 8 - Group 5 Sports Cars
• 8 - Mini Challenge IROC
• 8 - Rally Car
• 8 - Modified Production
• 8 - F1
• 8 - Nissan GT-R Super Series IROC
• 8 - Slot.It Challenge
• 8 - AM
• 8 - GT
• 8 - LMP
Also, taking into consideration how we may not race every week - I can safely knock off about 4 weeks which totals (8 events x 6 groups) 48 for the list above.
Hope you'll enjoyed ~ for what this info is worth
