🔧Repair and Maintenance

$$x_r=Lay_{n}=Lay~Mining~per~Day[Lev.\alpha]$$

$$Refair~Cost=x_r*((100-Durability)/10)$$

Buildings produce less $Lay 007 after a certain amount of time. As a result, building owners need to constantly repair their buildings. The cost of repairing a building depends on how much $Lay 007 it produces, and owners can only repair it if they pay for it.

Durability	Mining Efficiency
90 < Durability ≤ 100	100%
80 < Durability ≤ 90	90%
70 < Durability ≤ 80	80%
60 < Durability ≤ 70	70%
50 < Durability ≤ 60	60%
40 < Durability ≤ 50	50%
30 < Durability ≤ 40	40%
20 < Durability ≤ 30	30%
10 < Durability ≤ 20	20%
0 < Durability ≤ 10	10%
Durability = 0	0%

Note: A building's Durability is reduced by 0.1667% for every 'Get Lay' (based on 4 hours).

Note: When a building is leveled or tiered up, it is constructed as a new building(100% Durability).
