Crystal aging per year

WebCrystal aging tends to be logarithmic, meaning the maximum rate of change of frequency occurs immediately after manufacture and decays thereafter. Most of the aging will occur within the first year of the crystal's service life. Crystals do eventually stop aging ( asymptotically ), but it can take many years. http://www.mti-milliren.com/MTIPapers/Ext_Aging_Perf_Results.pdf
