I feel like it's because of the large well inside the head of the dramm, until that fills and pressurizes a bit it just pours out. I only have the black head at the moment though it doesn't look that much better on the red. I may cut mine in half remove half an inch or so of height and put it back together. Then see if that improves things.
That in combination with the number of, and size of, holes in the head. You need to bring in enough water that the waterflow is over capacity of the holes.
You certainly are entittled to your opinion but did you ever consider how Junipers in desert climates receive water, the Red Woods on the Coast and in the Sierras, and the Pines in the high mountains?
You're "enttitled" to ask questions wherever you'd like on this board as well, even if your question pertains to the most minuscule portion of what I wrote. But yes, I know that plants are watered by rain (or dew) that generally falls from above (or at least wets the foliage). I also know that plants growing in the desert, on the Coast, in the Sierras, and in the high mountains tend to have a more extensive rootball, and generally more vigor than a plant in a pot ...and likely some adaptation that allows them to live wherever it is they're getting rained on (or "dewed"). Noting that fungus tends to target plants in a weakened state, I try to avoid wetting the foliage any more than I have to. I've noticed positive results from doing so.
This.
Junipers can take up to 1/3 of their water needs through the foliage though.
That's my go-to wand
