Ive never really paid close attention, but when i neatly stack rounds in my truck i know its safe to say the volume i have will be the same when split. Of course im one of those "jigsaw puzzle" stackers too! I usually figure roughly 15% of space in an average stack is air.
That's been my experience. I'm a loose stacker so slightly more. I just stack. I don't think about it or make adjustments, except cross-stacking ends. Big air gaps between rounds = many small ones between splits.
Well, you found the prize! According to that guy, he says it's "close" to the same but, first, he said that after it is split and stacked, it was five inches taller than the trailer would hold and he started off with the rounds in there being dead level with the top of the sideboards. According to his test, after splitting, it takes up MORE space, not less. It would be interesting to see someone do the same experiment and stack the splits as tightly as possible.
At the 5:00 mark he measures the rounds as being mostly above the trailer sideboards. We also don't know if he drove the rounds and the splits down the road for equal measures of settling of contents.
I seem to recall someone posting another video here a while back that had the same results IIRC...I thought it was Life in Farmland, but I couldn't find it so...
Yes, it seems I also remember someone who sold wood by the pickup load and had 2 different prices if the load was stacked or loose. I just don't remember who or when that was.
