The Whole Earth Telescope collaboration is build solidly on the interest of the participants. One of the goals of the collaboration is to produce a high signal to noise, as continuous as possible, light curve for a selected target. During the nearly 15 years of existence the operation of the network has been based on what the members have been able to provide of local funds for their own participation, in addition to NSF grants to run the headquarters activities. This has led to a very uneven geographical distribution of participating groups and observatories. An analysis of the coverage of some of the last WET runs shows that we still have large holes in the coverage, and this leads to aliasing and loss of precision in our final products.
