Just go on IITC and look at what players are doing in busy areas. Here is literally the most recent action in my area;

"10:29 <berniemh> linked Tasman Bridge from a Lookout to The Hand of Change 10:29 <berniemh> created a Control Field @Tasman Bridge from a Lookout +1 MUs 10:29 <berniemh> linked Back in Time 1975 to The Mission to Seamen Hobart Station 10:29 <berniemh> linked Back in Time 1975 to Plastic Flowers 10:29 <berniemh> created a Control Field @Back in Time 1975 +7 MUs 10:29 <berniemh> linked Back in Time 1975 to The City Desert 10:29 <berniemh> created a Control Field @Back in Time 1975 +11 MUs 10:36 <berniemh> linked Rose Bay Foreshore Park to Tasman Bridge from a Lookout 10:36 <berniemh> linked Rose Bay Foreshore Park to Back in Time 1975 10:36 <berniemh> created a Control Field @Rose Bay Foreshore Park +1 MUs 11:07 <berniemh> linked Rosny Hill Nature Reserve to Clarence Foreshore Trail 11:27 <berniemh> linked Rosny-Montagu Bay Coastal Reserve Sign no. 3 to Rosny Hill Lookout 11:28 <berniemh> created a Control Field @Rosny-Montagu Bay Coastal Reserve Sign no. 3 +2 MUs 11:28 <berniemh> linked Rosny-Montagu Bay Coastal Reserve Sign no. 3 to Rosny Hill Lookout Track 11:28 <berniemh> linked Rosny-Montagu Bay Coastal Reserve Sign no. 3 to Plane Propeller 11:28 <berniemh> linked Rosny-Montagu Bay Coastal Reserve Sign no. 3 to Clarence Foreshore Trail 11:28 <berniemh> created a Control Field @Rosny-Montagu Bay Coastal Reserve Sign no. 3 +1 MUs 11:31 <berniemh> destroyed a Resonator on Clarence Foreshore Trail 11:31 <berniemh> deployed a Resonator on Clarence Foreshore Trail 11:31 <berniemh> captured Clarence Foreshore Trail 11:31 <berniemh> linked Clarence Foreshore Trail to Rosny - Montagu Bay 11:32 <berniemh> linked Clarence Foreshore Trail to Rosny Coastal Reserve 11:32 <berniemh> created a Control Field @Clarence Foreshore Trail +2 MUs 11:33 <berniemh> destroyed a Resonator on Montagu Bay Reserve 11:33 <berniemh> destroyed a Resonator on The Bridge Has Come Down 11:33 <berniemh> destroyed a Resonator on The Bridge has Come Down 11:34 <berniemh> deployed a Resonator on The Bridge Has Come Down 11:34 <berniemh> captured The Bridge Has Come Down 11:34 <berniemh> captured The Bridge has Come Down 11:34 <berniemh> deployed a Resonator on The Bridge has Come Down 11:34 <berniemh> linked The Bridge has Come Down to The Bridge Has Come Down 11:35 <berniemh> deployed a Resonator on Montagu Bay Reserve 11:35 <berniemh> captured Montagu Bay Reserve 11:36 <berniemh> linked The Bridge Has Come Down to Montagu Bay Reserve 11:38 <berniemh> created a Control Field @Back in Time 1975 +9 MUs 11:38 <berniemh> linked Back in Time 1975 to ANZAC Artillery 11:38 <berniemh> created a Control Field @Back in Time 1975 +14 MUs 11:38 <berniemh> linked Back in Time 1975 to ANZAC Park Lindisfarne"

So in 9 minutes Berniemh got 9 fields, 17 links, and 3 captures.

That's 9 x 1250 + 17 x 313 + 2000 x 3 (assuming he modded) + the AP from the destroys, which we can't calculate (because intel no longer reports on every destroy). So 22571 AP in 9 minutes. or 2508 AP per minute, or 150,473 AP an hour + AP from destroys. And he's not playing in a particularly high density area, most of the portals were already his colour, and he's driving, so is losing time having to stop at each portal. Go and look at any city and you'll see players scoring AP at this rate or higher.
