I was figuring out some GT League Stats last night;
There's currently 151 events (50 Beginner events, 53 Amateur events, 39 Professional events, 9 Endurance events)
Total prize money on offer for complete each event once in the specified class of car, without clean race bonus: 12,373,000 Cr.
Winning each race in a lower class of car than specified (where allowed) would yield approx. 13,566,600 Cr. (assumes 1-2 classes below specified, excl. one make or Gr. races)
And, adding clean race bonus to every event (nearly impossible I'm sure!) as well as the slow car bonus would yield 19,743,100 Cr.
... so if you race GT League, in the slowest cars you can manage for each event, and do it cleanly, you can end up with nearly 20,000,000 Cr !
The most used circuits in GTLeague are
Tsukuba: 9 Races
Suzuka GP: 8 Races
Nüburgring GP: 7 Races
Monza (No Chicane) & Interlagos: 6 Races
There's currently 10 layouts not used in GT League, and 19 circuits are only used once.
The highest payouts per mile ** driven (assuming no bonuses):
Nostalgic 1979 @ La Sarthe: 9,489.9 Cr. /Mile
Nostalgic 1979 @ Monza: 8,938.6 Cr. /Mile
Lamborghini Cup @ Sainte Croix C: 8,352.3 Cr. /Mile
La Fest Cavallino @ Brands GP: 8,163.3 Cr. /Mile
Mercedes AMG GP @ Nürburgring GP: 7,500 Cr. /Mile
.. the average payout for each race (assuming no bonuses) is 3,419.4 Cr. /Mile
**I haven't got around getting a reference lap time yet for most events, so I have no real stats about time taken except:
Lowest credits per second (so far): 41 - Sunday Cup Race 1 - Northern Isle
Highest credits per second (so far): 372 - Nostalgic 1979 Race 2 - Circuit de la Sarthe
My Stats at the moment are 164 wins across 127 of 151 available races. Minimum prize total (excl. bonuses)12,904,000 Cr.
