From: Linus Torvalds Date: Wed, 9 Nov 2011 16:06:17 +0000 (-0800) Subject: Fix up the statistics page use of pressure data X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=66c04f4f47f1f8fc55b3cc81df67acac1aa72b8f;p=ext%2Fsubsurface.git Fix up the statistics page use of pressure data The statistics page calculates air use separately, and also needs to be fixed up for the split of the pressures into sample-vs-start/end.
