How are the glyph hack bonuses calculated?

Did anyone come across a formula for the calculation of the glyph hacks? There seem to be many questions and attempts at it but I couldn't find any definite answer.

Solution 1:

The formulas in this post on glyph hacking are based on extensive field testing.

Relevant part from the post:

+------------+--------------------+------------+
| Portal lvl | Perfect hack bonus | Time limit |
+------------+--------------------+------------+
|          1 |               +28% |        20s |
|          2 |               +40% |        20s |
|          3 |               +55% |        20s |
|          4 |               +55% |        19s |
|          5 |               +55% |        18s |
|          6 |               +80% |        17s |
|          7 |               +80% |        16s |
|          8 |              +112% |        15s |

Hack bonus:

Speed bonus:

AP:

AP_bonus = 20 × P × 2^{0.5×G_correct}

AP = AP_base + AP_bonus + B_speed

where:

• P is 1 if all glyphs were drawn correctly and 0 otherwise (P = ⌊G_correct ÷ G_total⌋),
• B_hack is the hacking bonus,
• G_correct is the number of glyphs you got correct,
• G_total is the total number of glyphs in the sequence,
• B_perfect is the perfect hack bonus corresponding to the number of glyphs in the sequence, as shown in the table above,
• B_speed is the speed bonus,
• T_left is the time remaining on the clock,
• T_limit is the total time you were given to draw the sequence, as shown in the table above,
• AP_base is the amount of AP earned for correctly-drawn glyphs,
• AP_bonus is bonus AP earned for drawing all glyphs correctly,
• AP is the total amount of AP earned from the glyph hack. (Note: Does not include AP from hacking enemy portals.)

Example: Suppose you perform a perfect glyph hack on a L7 portal with 5 seconds left. Your hacking bonus would be 10% × 4 + 1 × 80% = 120% (4 correct glyphs and perfect hack bonus). Your speed bonus would be 1 × ⌊100 × 5 ÷ 16⌋ = 31% (5 out of 16 seconds left). Finally, you would earn 8 glyph hacking points and 50 × 4 + 20 × 1 × 2^0.5×4 + 31 = 311 AP.
