Not too bad from someone who only flown 2 focus. Few addendums / fixes after reading.
If you dont have enough cap, you broadcasted but did not receive any: at 10% cap turning off everything that consumes cap and keeping the hardeners on-and-running is standard procedure. This does include turning off your guns.
Most dangerous thing about bumping AAA is to get it out of position and thus getting the whole logi squad out of position, cuz they are also anchoring on AAA.
The only Sansha ship where snipers HAVE TO sit still in order to hit it is the Mara Paleo. That guy is so tiny, you need as much tracking as possible.
NRF is the one site where you will be struggling a bit with ranges as a pulsemare. Leshaks should be around ~15 kms from targets. A pulsemare should be around ~25 kms from those spawning 2nd and 3rd wave Antems. So Pulsemare should be between AAA and Leshak, closer to sansha, but still not as close as a Leshak optimally. Honestly a Beam Mare could just do the exact same with constantly using Gleam, cuz its kinda similar optimal.
Honestly i would not try to actually change scripts inside a site ever. Maybe while you are in warp, but def wouldnt turn off the TC in site, unless you are desperate to save cap or you are comfortably bashing a tower on optimal range.
Cuz you are going to forget to change script and/or turn them back on. Trust me. You will.
Shooting with a sniper is actually the simplest thing ever. Follow tags. A-I ->1-9 -> XYZ , never-ever J.
DPS and Leshak even more so can be a bit different cuz of application, but you are a sniper you should be applying just fine all the time. So: AS A SNIPER YOU ALWAYS, ALWAYS, ALWAYS FOCUS FIRE AND STRICTLY FOLLOW TAGS!
The only exception is the explicit voice command of FC, if FC wants you to shoot something different. Thats it. No other exception, ever.
Out of the 3 sites only 1 (NRF) has more than just a few letter tags anyway. So in 2 sites you will mostly shoot number tags. In order.
How to improve your cap :
-Get a shinier fit. Get X-type 500MN (biggest help you ever get for cap as an item), get faction CPR (Cap Power Relay).
-Get the Inherent Implants 'Squire' Capacitor Management EM-806 implant. It is super-great.
-Improve your skills! These are all helpful about this order: Controlled Bursts, Capacitor Management, Capacitor Systems Operation, Capacitor Emission Systems, High Speed Maneuvering, Acceleration Control, Warp Drive Operation,
-Stagger your active modules, like the hardeners, remote cap transfers, tracking computers. They will consume slightly less that way, also staggering hardener is safer if you drop down to 0 cap anyway (standard procedure).
