Economic Analysis

• The earning per day per square is : 0.21 (assuming perfection collection every 7 hours, which is likely impossible)
• The theoretical net profit, assuming 3 collections per day and a net investment of 179, is 101%. This is slightly lower than that of the Crystal Rose which was 111% (return of 240 on a net cost of 114).
• However, on a per square basis, the Crystal Rose was superior as it takes up 9 squares compared to 16 for the Crystal Waterfall.
• Crystal production from the crystal waterfall was due to expire on 21 March 2013 but didn't actually expire until 1 April 2013, a bonus period of 11 days, equivalent to  37.
