Almost falling off my chair laughing here.
Very simple:
100% = 1.
130% = 1.3.
I was under the impression that bonuses multiply, so:
1.30*1.35 = 1.755
1.755*1.50 = 2.6325
Therefore, 100*2.6325 = 263.25, which is the percentage increase.
First of all, in accordance with YOUR math, it would be a 163.25 percentage increase. I’ll leave the logic for you to figure out on your own.
Now for the actual numbers:
Base speed: 750m/s (T2), 863m/s (T3), 938 m/s (T4), 1013 m/s (T5).
Possible increases: T2 and up: booster circuit (35-50% at cost of 20% more spread) R6 implant (30% at cost of losing 50% more crit damage). No other bonuses available except for bonus on premium R9 tackler parallax.
So we have a base increase of 50%+30% across tiers at maximum, which requires a significant cash injection every game (most people including myself fly with mk1 and 35% bonus on plasma but w/e). Implant requires a massive damage sacrifice, especially for gunships with their aiming overcharge. Downsides are obvious.
Theorethical maximum:
T2: 750m/s*1.8= 1350m/s
T3: 863m/s*1.8=1553.4m/s
T3 parallax only: 863m/s*2.15=1855.5m/s
T4: 938m/s*1.8= 1688.4m/s
T5: 1013m/s*1.8=1823.4m/s
The actual real life usage in most cases (i.e. ESB squads et al, not losing massive amounts of damage or investing 15750 credits into booster every game at T5)
T2: 750m/s*1.35= 1012.5m/s
T3: 863m/s*1.35=1165.1m/s
T4: 938m/s*1.35= 1266.3m/s
T5: 1013m/s*1.35=1367.6m/s
Feel free to point out the problems with the math.
And in actual real life, engaging with weapon at more then 2 kilometers will result in missing every shot against everyone but facetanks who facetank everything and refuse to dodge, probably because it’s against their religion. Then there’s the fact that weapon’s optimal range is actually only about 2 kilometers without horizon modules in the first place.
