Gran Turismo 4: RSC% "Speedrun" Explained

The RSC Rally Raid, won from Capri Rally Easy, enables the easiest progression skip in Gran Turismo 4 with its sell price of 265,624 credits. What's the fastest possible way to obtain and sell it at the start of a playthrough? With the help of Gran Turismo 3, I planned out a route and attempted to speedrun this brand-new, unofficial category of "RSC%".

I played the NTSC-U versions of both Gran Turismo 3 and Gran Turismo 4 using PCSX2 1.7 nightly. I used Silentwarrior112's GT4 HD HUD and UI retexture pack, which can be found here: https://www.gtplanet.net/forum/threads/gt4-hd-hud-and-user-interface-texture-pack-for-pcsx2.417873/
