This trinket on live states:
Equip: Your spells have a chance to conjure a typhoon that travels towards enemies dealing 3473 Nature damage and grant you 64 Haste for 15 sec, up to 258 Haste.
In the Mr Robot Sim:
Equip: Your spells have a chance to conjure a typhoon that travels towards enemies dealing 3473 Nature damage and grant you 123~1 Haste for 15 sec, up to 492 Haste.
Not sure if the correct value is being used in the code, but the tooltip value in the sim is definitely wrong, and the trinket seems to be overvalued for a few of my characters (Use this instead of a socketed 455 Music Box for example) which seems unlikely at the correct stat values.
