The advantage is that no cumbersome and inaccurate graphically fitted R is required.

Worst, this wasted piece affected calculated dome volume (badly under-estimated).

Apropos "carefully fitted": what about this idea?

1. Assume an elliptical dome top. But do not enter its height Vo.
2. Instead enter a max. allowed liquid level (this can be the hatch height, or a limit set by the manufacturer) and the corresponding max. volume.
   Calculate Vo from this.
   

In our example the tank may have an allowed liquid level of 215" with a volume of 14500 gallons. For an elliptical dome top this means Vo = 34,8942".

This way we get:

Code:

level    volume
------------------
 192"    13113 gal
 198"    13532 gal
 205"    13988 gal
 210"    14270 gal
 215"    14500 gal

How do you like that?
