[[With no deaths, this raid will give approximately '''%s''' contribution points%s. With a raid level of '''%s''', this equates to a '''%.4f%%''' chance of receiving a purple drop%s, and a '''%.4f%%''' chance of receiving the pet%s.

This estimate is not exact, and may not match your true point total for various reasons, including:
* Deaths (the penalty for deaths cannot feasibly be estimated because it depends on how far you've gotten in the raid)
* Walk the Path levelling order (this assumes the order is Ba-Ba, Kephri, Zebak, Akkha – different orders may result in very marginally different average points)
* Higher or lower healing from Kephri's shields than estimated (this assumes that the shields mostly regenerate both times, but in good teams they may not, resulting in faster kills but ~2%% fewer total points)
* Additional P2 Warden cycles (this assumes "2-down", but "3-down" results in about 3%% more total points)
* Challenge room trap failures
* Precision loss due to integer truncation in RuneScript (estimated 0.5-1%% point loss)
%s
If you are doing this type of raid repeatedly, try comparing the estimated normal loot to the amount you actually tend to receive. For example, if you are consistently getting 10%% fewer coins than predicted here, your purple chance and pet chance will also be 10%% lower than predicted.]],
