Yes list etc. is always figured. Just more time consuming depending how many fixture you can get on lift and going up/down on lift more time than working off ladder.I would simply assign a time allowance per light, to include any furniture moving, as well as time on the lift, plus the lift rental itself.
Some lifts allow the lift to move when the platform is elevated...Are you thinking that the lift is faster or slower than using ladder?
The learning curve gets remarkably less steep when you finally read the fine manual! "Oh! You put the base plate up and THEN you install the driver!"For me hanging fixtures is one of my least favorite jobs. But, usually the first one (for example )takes 25 min the next 20 min then your doing the rest in 15 min theres a learning curve r to everything......at least for me.
