[horse racing] Data in *event_id* file precisely the same as in 1.market_id?

[fdsafds]

Is all the data in the main file of an event - $event_id - precisely the same as in 1.$market_id?


Is the only difference that the main file - $event_id - contains all the data from all the 1.$market_id files in the directory combined? And no new data or more detailed one.



In other words, all the data available in historical data of an event can be parsed from the main file only?

Yes, this is correct. The event file contains the marketId's for the event interleaved with each other and there is no new data or more detailed data. You can choose to parse the event file, or if you are only interested in specific types of market WIN, PLACE, etc), the marketId files individually.

Got it.

Is it safe to assume that in any given day any horse can only participate in one, and no more than one market/race?

Yes, it is safe to assume that on any given day any horse can only participate in one race.

Got it.

As I've understood, "market.id" is unique accoss all the historical data, namely, each data/event contains "markets"/ids that never repeat.

Whereas "runner_id" may appear on different events/dates.

Right?

[BetfairDeveloperProgram]

Yes, correct on both points
