If you are refering to the "* (Strong Buy) 1.0 - 5.0 (Sell)" footnote, it is the definition of the recommendation valuation:
Strong Buy - 1
Buy - 2
Hold - 3
Underperform - 4
Sell - 5
It is not the number of analysts. Value of 2,5 in the valuation would mean a recommendation between Buy and Hold for example.
