The notation is _very close to_ the ["Six Fastest" system](https://www.rallynews.net/pattersonpacenotes/systemtypes.asp). There are some differences between how the notation is described and used between DiRT Rally and its sequel, DiRT Rally 2.0. > This is how the differences in DR2 are given. ![image.png](${await FileAttachment("image.png").url()}) ### Corners In ascending severity: ``x6, x5, x4, x3, x2, x1, SQx, HPx, ACx`` where ``x`` is either ``l`` or ``r``. > DR2 puts the number first. Also, the severity changes. E.g., l5 would now be 6l: `flat, 6x, 5x, 4x, 3x, 2x, 1x, sqX, open-hpX, hpX`. To cover the same spectrum, a previous 6 is now called flat, and acute corners become hairpins. Corners can be ``long`` or ``hlong`` (half long), some are `immediate`. > DR2 corners can be `short`, `long`, `verylong`, `extralong`, or `extraextralong`. Many are `unseen`, some `sudden`. They can tighten to a higher severity, ``>``, or open to a lesser one, ``<``. > In DR2 it is also called if the road `opens` or `tightens` through a corner. > DR2 will call out if a corner benefits from an `early` or `late` turn-in/apex, or if it `continues` past a given way point. ### Road geometry The road can be ``open`` or ``tight``, form ``dent``s or (``long``) ``cr``ests. > DR2 calls out `dip`s instead of dents. Crests are often followed by a ``jmp`` (jump), which might only happen at certain speeds: ``jmp?``. Crests/jumps can be particularly ``small`` or ``big``. Bad ``camber`` means a section or corner that requires a certain line and perhaps less speed. ``bmp`` denotes bumpy sections. ### Car placement Drivers can be advised to stay in the middle of the road or left or right of the middle: ``keepm, keepl, keepr``. In corners, calls are made to ``keepin`` or even ``cut`` the corner. > DR2 sometimes suggests a `small-cut` or a `big-cut`. ``dontcut`` means to stay clear of the inside, ``keepout`` advises an outside line through a corner. ``line`` means taking a sequence of one or more corners straight. ### Road boundaries ``gate``s, ``post``s, ``tunnel``s, ``bridge``s require the driver to stay off the edge of the road. ``rock``s, ``log``s, ``ditch``es, ``bank``s can be placed on the inside, outside, or exit of a corner: ``-in, -out, -exit``. This is often combined with a placement call. (Tight) `chicane`s ask for a specific speed and car placement, depending on a `-left` or `-right` entry. `layby`s can offer more space to one side of the road, but might also mean less space due to parked cars. `bale`s are used to artificially tighten a corner. ### Change in road characteristics The next section can go ``[up]`` or ``[down]``(hill), it ``[opens]`` and ``[narrows]``. A `[water]` splash might require to switch on the windscreen wipers, while `[grid]`s can jerk the steering wheel. The road can be covered by ``[ice]`` patches. For longer sections, calls are made when `[ice]-starts` or `-clears`. > DR2 distinguishes `[snow]` from ice. It also calls out the transition to `[gravel]`, `[tarmac]`, and `[cobble]`. ### Orientation ``Junc``tion, ``turn``, and ``cross``roads denote segments where the driver must take care not to take the wrong way. ### Note succession ``/`` (over, past, for, through) connects different characteristics that occur simultaneously. Quick successions of stage characteristics are indicated by simple enumerations in a single line. Otherwise, a number is used representing distance between characteristics in meters: ``60, 80, 100, 130, 150, 200, 300, 400`` ### Driver attention Caution is advised by ``!``. This can be combined with advice of ``slowing`` or ``braking``. ``deceptive`` warns the driver, e.g. not to succumb to a wrong way. ``finish`` ends the stage and pace notes. > In DR2, the pace notes continue until the driver is to `stop`.34:[{"id":"4cb06b9f5c8b860386de28863403e9428738310e1ea216b40dfd2775c81e2d062ed0b21c4beb520e6400f3f607a5db45e099edd53c1642d2958ac05d6f38ab4c","href":"https://static.observableusercontent.com/files/4cb06b9f5c8b860386de28863403e9428738310e1ea216b40dfd2775c81e2d062ed0b21c4beb520e6400f3f607a5db45e099edd53c1642d2958ac05d6f38ab4c","name":"image.png","type":"image/png","lastModified":1648168938287.061,"size":5033092}] 31:{"id":"35e6de1711f95ba0","slug":"dirt-rally-pacenotes-reader","title":"DiRT Rally [2.0] pacenotes reader","thumbnail":"3cba80f31b8bc6ca270ac2af7e1cedb7f54529a1d006fe0d39d7da2be7cbea04","access_level":"public","create_time":"$D2022-03-24T00:59:43.868Z","update_time":"$D2023-07-26T23:40:13.789Z","view_time":null,"first_public_time":"$D2022-04-02T06:05:27.611Z","fork":false,"stars":1,"starred":false,"owner":{"type":"team","id":"cc48459e4293f942","login":"mjbo","name":"Max Bo","avatar_url":"https://avatars-next.observableusercontent.com/05ae9baba40510a4a22fa7d179f29dd4ffd85fcff859c54a31d42e166ae61dfa","tier":"starter_2024"},"version":489,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"5bb83a6e9493ea1d","login":"mjbo","name":"Max Bo","avatar_url":"https://avatars-next.observableusercontent.com/05ae9baba40510a4a22fa7d179f29dd4ffd85fcff859c54a31d42e166ae61dfa","tier":null}],"members":[{"type":"individual","id":"5bb83a6e9493ea1d","login":"mjbo","name":"Max Bo","avatar_url":"https://avatars-next.observableusercontent.com/05ae9baba40510a4a22fa7d179f29dd4ffd85fcff859c54a31d42e166ae61dfa","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":true,"trashed":false,"lapsed":null,"subscribed":null,"forks":0,"collection":{"id":"a5615d262872a60a","slug":"misc","title":"Misc","owner":{"id":"cc48459e4293f942","login":"mjbo","name":"Max Bo"}},"type":"notebook","body":{"title":"DiRT Rally [2.0] pacenotes reader","cells":[{"id":0,"value":"# [DiRT Rally](https://en.wikipedia.org/wiki/Dirt_Rally) [[2.0](https://en.wikipedia.org/wiki/Dirt_Rally_2.0)] pacenotes reader\n\nThis notebook takes [pacenote](https://en.wikipedia.org/wiki/Pacenotes) transcripts compiled by Max Bechtold's project [`dirt-rally-pacenotes`](https://github.com/maxbechtold/dirt-rally-pace-notes) and expands some of the abbreviations into a beginner readable form. \n\nIt was built because I thought it would be fun to read out pacenotes for my housemate while they played [DiRT Rally [2.0]](https://en.wikipedia.org/wiki/Dirt_Rally_2.0), rather than letting them listen to the in-built automated co-driver.
