that in turn leads to questions about your coverage. You can likely see 1090 much further out than 978 (which fly lower). For me, I have about 5-10% UAT count compared to 1090ES. But I can see 1090 all the way from Bakersfield to the Oregon border (a 10-ish hour drive by car). UAT I can see from Sacramento down to San Jose or so (about a two hour drive by car). That affects the fairness of the comparison
