almost positive. the day of or the day after ov your temp will rise and will keep rising over 2 more days and this is called the temp shift. it will likely continue rising but the first three are the important ones. The first 3 higher temps must all be at least 0.2'c or 0.4'f higher than the previous 6 temps. look at this for example http://www.tcoyf.com/media/p/1490921.aspx
