annotate Discovery/Src/data_central.c @ 293:02d10d955be2 div-fixes-6
bugfix, consistency: show deco, NDL after 1 minute
1 letter fix. VPM showed NDL data after 10 seconds, and Buehlmann after 60
seconds. And as this type of data is fully irrelevant during the first minute
(at least), make VPM and Buehlmann consistent and display NDL after 60 seconds.
