+1 to
ivegotalobon 's solution.
This is a clean-up of his solution, using my own experience.
I was myself confused when I read his solution and the comments.
- The "expired invite" exploit works a treat, is SUPER easy,
but requires 2 boxes and 2 gold accounts.
- Autosave ON or OFF:
It works with Autosave off, but it means you do the whole season in one sitting.
- The EASY race is very important:
It will set all the points you will make in the season,
if you chose to only actually race the one track you prefer.
It is better if you try and push the drivers of the top teams in walls,
to make them loose time and score less points during that one race.
It would save you time, BUT this is not NECESSARY.
So the process is:
1 - Set Autosave OFF
2 - Start season on EXPERT
3 - Race or crash the tracks until you get to your chosen track
- if you race, make sure the settings are on EXPERT when you pass the finish line
- if you crash, make sure the setting are on EXPERT when you do
((make sure to change the assists settings until the first line says "EXPERT"))
ON YOUR CHOSEN TRACK
4 - Start the weekend on EASY
5 - Qualify or not (no bearing)
6 - Race, win, and if possible take out the main rivals
(taking out rivals would only help you get to the end quicker)
NOTE:
I personally forgot to reset the braking assist prior to finishing the EASY race,
it did NOT stop me from getting the achievement at my first try.
(only observation from my own experience run)
LOOP LOOP (don't worry, just read on)
7 - At the end, do not get finger jittery, and stop AT the CONSTRUCTORS screen
8 - use the "Expired Invite" glitch
- receive an invite (from other box other account)
- accept the invite and have the second account quit the lobby straight after
(pretty much at the same time)
(I was pressing the accept on my main,
then pressing yes to quit on the other box,
so a portion of a second gap was working for me.)
- Accept the comment of "Connection Failure", Exit the Multiplayer mode.
9 - Back to Career
10 - Start same weekend again, on EXPERT
(you will have to change the setting the first time,
then it should be set by default for the next ones)
This will take you straight to RACE day now.
11 - Crash or get Disqualified
(I used both with no problem)
12 - If you crash, accept the crash with "Y", then Retire.
13 - NO finger jitters !!
THIS IS WHERE YOU USE THE LOOP. (back to number 7)
YOU DO THE LOOP OVER AND OVER AGAIN UNTIL YOU HAVE ENOUGH POINTS.
Once you have enough points:
(25 * number of tracks left) +1 more than the second in the leader-board at least.
14 - Keep Racing or Crashing for the rest of the season.
15 - The achievement will POP once you get out of the last race weekend.
16 - SAVE
