Abstract: In the Whole Earth Telescope (WET) observations of the sdBV PG 0014+067, made in 2004 October, we found a peculiar regularity of the pulsation frequencies reminiscent of asymptotic p-mode pulsation along with rotational splitting. This finding was amplified by adding additional modes found by observations with the WHT earlier in the year. To determine if this was a peculiarity of that star, we examined other sdBV stars that have extended-longitude coverage, and found a similar pattern in all of them. High-order p-mode pulsations (such as seen in the Sun and roAp stars) should not be present if our models of these stars and their pulsations are any guide to reality. The reasons behind this pattern are currently unknown.
