Through experimentation it looks to be the warning and critical thresholds expressed as MB --

[root at gemini plugins]# ./check_disk -w 10% -c 5% -p /
DISK OK - free space: / 2414 MB (33%);| /=4987MB;6660;7030;0;7400

7400*0.9=6660, 7400*0.95=7030

[root at gemini plugins]# ./check_disk -w 20% -c 10% -p /
DISK OK - free space: / 2414 MB (33%);| /=4987MB;5920;6660;0;7400

[root at gemini plugins]# ./check_disk -w 40% -c 30% -p /
DISK WARNING - free space: / 2414 MB (33%);| /=4987MB;4440;5180;0;7400

[root at gemini plugins]# ./check_disk -w 50% -c 40% -p /
DISK CRITICAL - free space: / 2414 MB (33%);| /=4987MB;3700;4440;0;7400
