I have two cases (amd950 being among them) succeeding in online registration without being actually being selected.

Basic:
$12,800
Get: 12,800+75,000 = 87,800pts = 5,853.33AM
$2.19/AM*

Overseas (ITC)/dining (Tiramisu and Tastie)
$12,800
12,800x3+75,000 = 113,400pts = 7,560AM
$1.69/AM

3x10x (online, Apple Pay, overseas on ITC (Plat V/M cards))#
$10,300
10,300 + 75,000 = 85,300pts = 5,686.66AM
$1.81/AM*

Tiramisu/Tastie on Apple Pay
$10,300
10,300x3 + 75,000 = 105,900pts = 7,060
$1.46/AM

eye HKD online/paywave/Apple Pay
$12,800
12,800x5+75,000 = 139,000pts = 9,266.66AM
$1.38/AM

eye overseas online
$12,800
$12,800x7+75,000 = 164,600pts = 10,973.33AM

*these rates apply on Visa Infinite/Unionpay Prestige at 87.5% bonus (AM conversion is /8 instead of /15). So divide these rates by 1.875 for VI/Prestige rates. Hence with VI/Prestige online or overseas, you get $0.966/AM

#CCB 939 onlineffline balancing formula

y=online
z=offline

(Assuming 5,000 target) 75,000 = 10,000 + (y-5,000)x8.39 + 2y
106,950 = 10.39y
y=$10,293.55 (stated as $10,300)

Expand to include offline spending z: 75,000 = 10,000 + [(y+z)-5,000]x8.39 + 2y
106,950 = 10.39y + 8.39z

When you know z, solve for y. Or vice versa.
Note: y+z must be rounded up to nearest 100
