Games ult unit travel

Does anyone know gnars ultimate unit travel and range depending on location or enemy champion closest and farthest from gnar? Is there a difference in distance enemy will travel if enemy is in the middle? If enemy is farthest from direction where ultimate is placed (enemy unit is opposite of gnar ult arrow indicator)? Do they all travel max range regardless? Do they travel less range if they are at the furthest point facing ultra direction (on arrow indicator)? Please let me know asap! It's life and death.
