There are (at least) three ways to measure height of a mountain: height above a geoid, height above base, and furthest from the center of the earth.?ÿ Different mountains get on the list for different ones of these reasons.?ÿ
I think Dave's mountain is high above its base on the sea floor. Mountains near the equator gain distance from the center of the earth from the oblate shape of the earth. Everest is high above the geoid.

Yes, and biggest mountain takes on a very different meaning.?ÿ Biggest includes volume so a mountain with a large unique base can be classified as being bigger than a mountain that is higher but has a smaller base.
Terminology is key.
Once the structure is built over the pipe, the best you maybe able to achieve is 0.05', and that's on a new pipe.?ÿ Trying to obtain 0.01' accuracy on a pipe that has been in the ground for 50 years, is cracked, filled with various types of sediment is a fallacy.

There are over 100 mountains in Asia that are like 10,000 feet higher.

I put the smiley face on there because the Pacific volcano I live on is sometimes described as a single mountain (with 3 peaks), in an archipelago or oceanic mountain range.?ÿ With the highest point on this island at 13,400' and the base 17-18K' below MSL it makes it the tallest mountain on the planet according to your list.
Yup.?ÿ The details are all in the terminology used.
Wait.?ÿ So, if the lowest point in the US is the bottom of the Mariana Trench at around seven miles below sea level, does that mean that my mailbox is setting 1050 feet plus seven miles high?
