Completely impossible finish time.

Also just have 5 Dedimania-record, two of them are world record.

I don't believe that it is possible to go this much faster on this map, and the end sector is almost definitely impossible.

It seems possible (but extremely difficult/lucky) to make the last jump left towards/on top of the wall, and from there into the finish. The login has no other suspect entries as far as I checked, so I'm giving this one the benefit of the doubt.

Hmm, a .14s difference on a 16+ second track does not seem so clearly impossible, but another entry was definitely cheated. Housekeeping performed, thanks.

Yes, typical cheaty patterns on 5 tracks. Banned and all deleted, thanks.

Re: Report strange & suspect TMF records here

I'm not 100% sure about this but something sounds quite off to me, also sorry in advance for the long post but I want to write down a lot of thoughts about it because I spent a lot of time into this but I can't still explain how this was achieved.

I've hunted this track for a few hours because I thought there was a cut near a loop, and yes there is but it's very precise and you can still get caught up by the intended route before the end since it's a speed map with no slow downs except the end.

After beating the WR offline by a few hundreaths I checked the checkpoint times to see if anybody else has had this idea. Apparently everyone on the leaderboard has followed the intended route but the times on dedi2 are a little bit off: it has a slow start but it gains a lot on the last two checkpoints.

At first I thought it was made with another "cut" where you can take a booster on the restart route after a checkpoint to gain more speed (you can do that because the booster is placed after the checkpoint). I tried a little bit but I didn't get anywhere close to have more speed with that. Then I had a closer look to those checkpoint times and I was probably wrong: there's no sign of that booster, the entire save time cames in the last two checkpoints.

The turn before the second to last checkpoint is a dirt turn where you'll eventually slow down even if you drive full throttle, I leave an example video here from one of my runs. Before this turn this dedi2 is 1s slower than the WR and at least 0.3s slower than anybody else in the leadearboard. After that there's a time save of over 0.3s which sounds really suspicious considering how popular this map is and how many players have tried it multiple times. But the biggest time save it's right after where the remaining gap is closed to less than a tenth and that part consists of only a loop and a wide range turn.

The only way to gain time there is just to exit from dirt section with a better speed but the amount of speed you'd need to have to be that fast is just ridiculous. There's a "cut" (quotes because it's actually slower) on the dirt turn where you can drive on the inside and cut a portion of that segment, as it's shown in this other video still made by me.

This can explain the 0.3s gain on the second to last checkpoint but the problem is that with this route you have way less speed, in fact the run in the video lost 1.3s afterwards. If someone wants to be really creative, they might think about a bugslide on dirt to mantain a lot of speed but I still have doubts about it:
1. First there are cacti in the middle of the road which force you to take that exact line;
2. The only way to trigger that is to climb a little bit the dirt hill and hope for the car to get in the correct position. However the hill is extremely bumpy and I haven't gotten even close in all of my attempts;
3. Even if you get it, you still have to re-align your car which makes you lose a little bit of speed.




Being unable to find any reasonable explaination I went to check the other records of this player: having only 20 dedi and some of them in highly rated speed maps doesn't really sound as a good beginning, but I didn't find anything weird about the chckpoints, except for one entry:

This, like the first map, is a quite known speed map but it's way more straightforward without any known cut. The end is a drop down from the road into the grass and here's a video example from my dedi. My end is not perfect but it's solid, the time between the last checkpoint and the finish is 4.05s, 9th fastest on the dedis. The second fastest time is 3.97s which is reasonable with a better ending and a slightly higher speed into the turn meanwhile the aforementioned player sits on top with only 3.73s in this segment.

I thought a bit on this end but again I couldn't find an explaination for such a time, even a grasslide seems out of question because you don't have a sharp angle to get an advantage from it and given the high speed it's less effective anyway.


My conclusion is that these two records are cheated (the others look fine) using a tool which gives you road grip on other surfaces: this explain why the strange behaviour is detected only in grass/dirt sections (to be fair the first map has other dirt transitions but they are full speed and they do not affect your speed).
Given the low number of records in relation to the competitive level of such maps this is probably a second/alternative account of some speed player (or someone coming from Tm2).
The two records were set only one day apart meanwhile the 20 dedis spawn over a course of 3 years, so it might just be a case of a player trying to use that kind of cheat just out of curiosity.

As I said in the introduction I'm not 100% sure about this and it could just be a series of unfortunate coincidences but my hopes on the latter statement are getting slimmer and slimmer the more I try the maps.
