What is the most honest estimate you can tell me? Three little words, “I don’t know”, that is the most honest estimate you have got because you don’t know. Anybody who pretends they know how long something is gonna take it is lying and BTW if you make a estimate date, you are lying. If someone comes to you and ask “can you get this done by Tuesday?” and you say “Yes” then you are lying. You don’t know that you can get it done by Tuesday unless you absolutely certain for some reason maybe it’s one line change and Tuesday is a week’s away.
