Yes and no. On one hand it is a really simple question. Every item we carry weighs something. I am trying to get the most comprehensive spreadsheet together I can for a realistic base weight. In doing so, I don't want to leave out those last minute things we often throw into the pack right before we hit the trail, or those miscellaneous items we "forget" to add. I have seen BPLers post some crazy light gear lists only to have members point out all of the essential items they left out. I am really trying to focus on that "hidden weight", especially the miscellaneous personal items that can really add up. Then I was looking at some miscellaneous consumables, and wondering how to best account for them. The devil is in the details.
In my original question, the Dr. Bonner's, hand sanitizer, sun tan lotion, and bug lotion all added up to 4oz, not including the containers. So my original question was where to record that four ounces? Under base weight? As a consumable? This has lead me to create a separate consumables spreadsheet, in an effort to better understand and save weight on that side of the ledger. Consumables seem to get a lot less attention than the items that make up our base weight. I suspect there are lots of hidden ounces there.
On any multi-day trip, I also check the actual weight of my pack, including all consumables, plus one liter of water, before I load it into the car. Of course, it always heavier than I estimated off of my spreadsheet. The hope is I can get closer to an accurate idea of my total pack weight as possible.
