The display discrepancy is due to the fact that the search filters are set to "Most Appreciated, This Week" which means that the number of appreciations for the past 7 days is showing rather than the total. You can always see the correct total number of appreciations for any given project by viewing the project then hovering your mouse over "info." You can view additional statistics by visiting Activity --> My Statistics.
PROFILE SHOWS FULL STATS FROM ALL-TIME
SEARCH DEFAULTS TO "MOST APPRECIATED THIS WEEK" (you can toggle to "all time" as well under the "Most Appreciated --> Time" dropdown)
