Mining Gank Math – Part 2

So now I (think I) have a basic idea on how common mining suicide ganks are locally, how quickly CONCORD comes to help, and the DPS of the common ganking hull. The key timings I have to survive are 8 (fresh CONCORD response) and 14 seconds (prepared CONCORD response).

The last step is looking at my tank – starting with the Procurer. This is the standard fit I’ve been using for a while.

Assuming VOID ammo, I created a damage Pattern in Pyfa for the Suicide Catalyst of 50% Kinetic / 50% Thermal damage, and applied it against the Procurer.

This gave it an EHP against the Catalyst of 58,551 and a Shield regen of 52.

(I know Shield regen is not linear, I’m just using a simple and basic allowance for it.)

So, using the basic calculation of

EHP / ((DPS x Number of Catalysts) – Shield Recharge) = time in seconds

I found it would take a minimum of 7 Catalysts to gank me in an 0.8 system if CONCORD had been prepared, or 12 if not. Overheating my tank, that increases to 8 and 13.

I guess that quantifies the risk. What does that really mean?

Thinking back at all the Killboard examples I looked at, while most of the ganks were by a small number of Griefers, it was common enough to see examples of a dozen or more Catalysts being used. My fit is probably safe enough.

Using all this new-found knowledge, I revisited my fit with view of adjusting the tank for Catalysts. What happened if I swapped the EM module out for Thermal, or Kinetic, or how about a Thermal, Kinetic and Adaptive Invulnerability? Turns out the last combination was the most effective.

That gave me an EHP of 80,418 and a shield regen of 81. Quite a jump. This small fitting change increased the minimum Catalysts to 9 and 16 respectively. Overheated, 12 and 21.

I tried different fits – with a Hull tank / rigs instead of shield. It gave the same sort of results but with a yield loss. The last big boost came from fitting a damage control but losing one of the Mining Laser Upgrades. That gave an EHP of 97,581, shield regen 93, for 11 and 19 Catalysts. Overheated, 14 and 25.

A minimum of 14 to 25 Catalysts to take out a 41M ISK ship and fitting. That seems a reasonable trade – and quite an increase from the original 8 to 12. More than 75% more effective.

This is the sort of thing I like about EVE. The complexity, the lack of certainty, how just a little bit of extra knowledge and a small tweak can make such a big difference. I’ll probably have someone point out a fatal flaw in my thought process. Until then – I’ll enjoy the little eureka moment.

To be honest I’m a fairly lightweight EVE player. I don’t see all the nuances, tricks and optimal approaches that some players seem to do naturally.  What a lucky gift they have.

Now I’ve publicly said where I’ll be mining and how my ship will be fitted. It will be easy to fit a counter and gank me. Probably not the brightest of my ideas – but I’ve seen my blog stats of late, so I figure I’ll be safe enough.

I was going to also look at the Skiff – but it isn’t necessary. A similar approach to fitting and some T2 rigs, and it can take more than 18 to 31 perfectly skilled and flown Catalysts to take it down.

The next step is to look at Alpha ganks and different sorts of DPS ganking ships and damage patterns – but I’ll stop with this.  It’s only a Procurer after all.
