There are many variables. The vibe, how the air is, what’s going on in other areas of your situation. I’m making some lemon potatoes at the minute, for example. Sometimes I boilethem for 5 minutes before I put them in the oven. Sometimes 10, or even 15. Sometimes I put the juice of one lemon, and other times two. Four cloves of garlic? Five or even six? How long covered in the oven and how long with the foil off? It all depends on the myriad of factors that are at play. Every day is different, so every blend of liquid should reflect this.
