Merxtremely High Effort Mapping

I tried the challenge of the Extremely High Effort Mapping Competition (https://www.youtube.com/watch?v=aTstaAK4kpI) but in Trackmania 2020 !

While driving the intended route the car must touch every single block that is placed in the map
The map’s weight must be a multiple of the total number of blocks placed (Number of block : 32 ; map's weight : 928 ; 32*29=928)
None of the blocks available in the editor can be used more than twice
The number of boosters placed in the map must be equal to the total number of checkpoints placed in the map (2CPs, 2 boosters)
Between passing each checkpoint the car must touch at least 15 blocks and the first checkpoint of the map must be passed within first 10 seconds of driving (16 blocks between CP + first CP in < 4s)
At some point in the map the car must stay in the air for at least ‘x’ seconds where 'x' is the amount of right turns in the map (1 right turn)
At some point in the map the car must reach the speed higher than ‘y’ times 100, where 'y' is equal to the amount of left turns in the map
(4 left turn, speed > 400 after second boost)
At some point in the map the car has to drive backwards for at least 2 seconds, but no longer than for 6 seconds (4s backwards)
The finish line must be placed within 2 blocks radius of the start line
Map must be built with vanilla editor
