From bb421a416dd894979e2335efea8db06b681f0dc8 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 20 Nov 2011 10:27:19 -0800 Subject: [PATCH] Revert "Correctly plot the tank end pressure if it was set manually" This reverts commit abdee5b1b8a97c641bca9bc2ebac9555c3e2ea54. There's no point in doing random hacks. Instead, do the intermediate pressure calculations with proper rounding instead of always truncating to mbar. With the math done correctly we have enough precision that the end result of the pressure interpolation doesn't have the kind of errors that caused Dirk to try to fix things up later.
