API:v2/commerce/exchange/gems with different quantities

[Zok.4956]

Hi,

 

how does this endpoint calculate the "coins_per_gem" when using different quantity values?

 

Examples:

 

https://api.guildwars2.com/v2/commerce/exchange/gems?quantity=10

{

"coins_per_gem": 1870,

"quantity": 18706

}

 

https://api.guildwars2.com/v2/commerce/exchange/gems?quantity=100

{

"coins_per_gem": 1978,

"quantity": 197839

}

 

https://api.guildwars2.com/v2/commerce/exchange/gems?quantity=1000

{

"coins_per_gem": 1981,

"quantity": 1981494

}

 

https://api.guildwars2.com/v2/commerce/exchange/gems?quantity=10000

 

{

"coins_per_gem": 1968,

"quantity": 19680532

}

 

All requests are made at the exact same time.

 

I understand, that with larger quantities there could be some rounding-differences. But this differences do not look like this.

 

Is there an explanation for this differences in the "coins_per_gem" value?

 

Thanks.
