I did not characterize or frame my analysis in the manner you suggest…I discussed the number of ground units destroyed by aircraft and the number of aircraft lost to all causes to achieve that tally.
When you are analyzing the exchange rate (kills versus losses) of aircraft and enemy ground units, you must factor in all of what killed the aircraft or you’ll have a botched comparison.
Actually, the main issue others seem to have with my posts is their very advanced nature…a lot of people here seem to be struggling to keep up. To your question, we cannot look at SPAAs’ effectiveness (the table doesn’t class SPAAs on their own).
The nearest analysis we can do is look at what all ground units managed. Even so, we can discuss it if you’d like:
Spoiler
Aircraft deaths to ground units (no type specified): 3,939 aircraft killed
Ground unit deaths to aircraft: ----------------------------> 6,219 ground units killed
By these numbers, the kill share of ground units versus aircraft is about 63% of the value of the kill share of aircraft versus ground units. More directly, the tally is ~10 ground units lost to aircraft for every 6 aircraft lost to ground fire.
Another important aspect that weighs in on this effectiveness analysis is SP costs; these vary widely, but GFs (even respawns) cost considerably less than aircraft.
Because the table does not specify the nature of the ground units, we must consider all types and their full range (which varies by match BR) because the reality of the data is that it could be attributed to any mix of them:
Spoiler
Ground unit costs:
- SPAA: 70-110 SP
- Heavy/Medium/Light Tank: 100-160 SP
- SPG: 90 to 130 SP
Aircraft costs:
- Aircraft (clean fighter without bombs/rockets/AP ammo): 480+ SP
- Aircraft (with bombs/rockets/AP ammo): >480 SP
Ground units require only about 15% to 33% of the SP costs of even the cheapest aircraft (nevermind more expensive aircraft) but yield about two-thirds the kill share of aircraft. Accruing 63% of the kill share for 15-33% of the cost is a marked advantage for cost-effectiveness. Furthermore, despite their lower costs, ground units possess the main means of influencing the match while aircraft lack this (capture point interaction).
Based upon this, we can see that a team could potentially lose multiple ground vehicles in the pursuit of destroying a single aircraft and emerge with the advantage as long as the aircraft ends up killed.
Back in 2017 (that data table is circa 2017), myself and numerous took advantage of the above realities…

…it was a strategy to coax the enemy team into aircraft…then gun them down with SPAAs and aircraft. By killing players in aircraft rapidly, they would have limited SP to respawn with and it’d often force them out of the match.
The above was prior to the 2018 SP costs changes, which have damped the effect of this strategy by allowing cheaper GF respawns…but someone like @JuicyKuuuuki really has the potential to carve up enemy teams’ SP even today.
As in the other analysis, ground units’ results are quite respectable.
