during taxi, engines run at idle, right
- it strictly depends on weight: the higher the aircraft weight, the higher is your needed N1 to taxi ...
- the ground idle mainly depends on whether you're using anti-ice or not: the "heavier" is the engine bleed, the higher the idle N1 commanded by FADEC to meet with the demand.
On the whole, the question ain't well formulated to be sincere ...
