Concerning the Lead Screws May Need Lubrication message

Hey there! I just received the Lead Screws May Need Lubrication message. I received my machine 4 weeks ago and haven’t printed more than 50 hrs on it. Is this a reasonable time period for this maintenance? The Wiki states “approx every 3 months”. What parameter do you suppose it’s using to justify the message? Increase torque needed to turn the screws, or simply an every 3 month reminder from time machine was built? Thanks, Stu
