Clarification on Bonus Heroes % please... (RE: std token)

So the posted probability of a bonus hero is 5%. But is this based on the TOTAL opened tokens? Or only the tokens opened that meet the requirements (3* and up)?


For example: for Standard tokens, the probability of pulling a 3* cover is roughly 3%. So is the probability of drawing a Bonus Hero from a Standard token:

0.15% (3% multiplied by 5%)

or

~3%

For Elite, the same question applies... Is the Bonus rate:
1.25% (~24% multiplied by 5%)
or
5%




(I'm in the progress of opening my cache of Standard and Elite tokens... I'll post my pull rates)

Standard Token Results:
140 Standard Tokens opened:
2 3* earned
2 Bonuses

tiny bit below average... my 3* open rate dropped to 2.56%


Elite Token Results:
183 Elite Tokens opened:
14 3* earned
7 Bonues

tiny bit below expected (9 bonues would've been 5%)

My sample size is too small, but it looks like it's 5% "TOTAL" and not related to the 3* covers. Good news!
