Some general advices.

• In most cases the edge of the road is slightly convex, and if you jump from it, you will fly a little further.
• Landing almost always takes your velocity, so sometimes it's better to go around an obstacle than to jump over it.
• In some places the floors have invisible protrusions that make you jump and lose speed, so try to memorize them and go around.
• Speed reduction after big jump landing can vary, and I'm not sure how to manage it. Just consider this when checking new strats.

Comments on my IL's:

1. Sparta (17.66) - nice, in tas you could change the motion vector when landing on the 14th second
2. Thermopylae (24.66) - could be better
3. Tauresium (17.98) - I go around to gain more speed for jumping
4. Wallachia (15.37) - pretty good
5. Frankish Empire (24.35) - very bad beginning (leftfornova's IL is about 0.8s faster at third jump), but reeeeally lucky edge landing at the end.
6. Vienna (36.10) - nice, but I think this level could be beaten by jump-rebound from the edge down below (https://imgur.com/a/OaaAejs). definetly could be tassed
7. Trento (23.92) - not much can be improved here. This level could possibly be tassed like this:()
8. L'Aquila (29.30) - avoiding a jump at the beginning allows you to gain more speed.
9. Rome (16.91) - not much can be improved here.
10. Florence (35.34) - I think you could accurately cut corner on 18th second. with tas you could cut corner further from it on the right (on 5-12s). Also, maybe this could be tassed better with jumping down below without going round.
11. Dijon (21.03) - hardest thing I've made! Also check this strat, maybe faster if made perfect: ()
12. Paris (36.91) - could be made much faster with better edge cutting
13. Angers (20.99) - pretty nice strat, but you need to get many smooth landings.
14. Lyon (25.75) - fuck this level :/ curved floors with invisible protrusions, that throw you up and eat up all the speed. could be made much better, especially at the end.
15. La Rochelle (53.31) - pretty hard level. You better slow down before rock-jumping, so you will spend less time falling. Also, take a look at leftfornova's 42s jump (), it's really good, because of speed redirection at landing.
16. Madrid (29.31) - the main goal is to gain more speed before big jump. Maybe you could jump more to the left, or better redirect your speed on landing.
17. Porto (34.78) - I have really bad ricochet after first jump, but I didn't find out how to do it without ricochet consistently, I have it like one of four attempts. Also, I think, you could land on the rock after big jump, and do big jump again.
18. Witches' Sabbath (17.80) - you could improve it by better landing, more to the right and without such loss of speed.

As a small note to the Trento comment: It seems that some timetrial levels do not have all of the castles walls extended with invisible barriers too (A timetrial of Wallachia that shows it: ).
