Rageknife interaction with crit modifiers

[LinSun00]

Rageknife passive:

Convert every 1% critical strike chance into 1.75 bonus physical damage [on-hit], capped at 100% critical strike chance, for a maximum of 175 bonus physical damage on-hit. This damage is affected by Critical strike modifiers.

What do they mean by "affected by critical strike modifiers" ? Test in practice tool and put results below.

Reminder: IE and rageknife cannot be built together

[LinSun00]

Yasuo/Yone

Passive:

• The crit chance is doubled AFTER it is already converted into on hit damage and therefore equal to 0. As a consequence, the doubling doesn't amplify the on hit damage of rageknife.
• The crit damage reduction doesn't affect the on hit damage for Yasuo, whereas it is applied to the on hit damage of rageknife for Yone.

  Senna

  Passive:

• The crit damage reduction (= 160.125/170) affects all on hit damage whether it comes from the crit chance granted by her items or her passive stacks.

  Fiora

  E second auto:

• The auto crits even with rageknife and applies the crit damage.
• The on hit damage is added after and not affected by crit damage.

  Jhin

  Passive:

• The 4th shot crits even with rageknife and the on hit damage is added after (unaffected by crit damage).
• The crit damage reduction (14%) is also applied to the on hit damage.

R 4th shot:

• Unaffected by rageknife.

  Shaco

  Q + passive (Backstab):

• This combo crits even with rageknife.
• As specified in shaco's spells, the additional damage from Q and from the passive are affected by crit damage.
• The on hit damage is added after and remains unaffected by the crit.

  Tryndamere

  Passive:

• The additional crit chance granted by fury is converted to on hit damage.

  Rengar

  Q + auto:

• The auto crits even with rageknife but he doesn't benefit from the spell's crit chance scaling (all his crit chance is converted to on hit damage).

As a general rule, it seems safe to assume that crit chance scaling works as intended and is nullified when a champion has rageknife. (only tested for rengar above, and caitlyn R)
