How long does it take?

Ok I am getting better at estimating how long field work should take and how long it will take me to get the data qa/qced and adjusted and ready for boundary decisions and then to drafting the PURDY plat or map etc.  

Do yall have a rule of thumb that is a ratio or multiplier of say a topo or mapping or even a boundary survey that takes 8 hours of field time should be drafted in 1.5 x’s more or less to have the final drafting deliverable completed. As a newbie to drafting I already know I am slow as molasses on a cold day. But I am trying to set myself some milestones as I learn and improve.
