Using Magnus in spite of convenience fee

[Anush]

Hello,
I would like to know under what situation you would used Magnus in spite of having a convenience fee for usage?

Let us assume that I do not transfer the points. So it would be 1.2% cashback. Is the following true?
1. For months where spends are below 1 lakh, using Magnus is beneficial when convenience fee is <1.2%.
2. For months where spends are 1 lakh, using Magnus is beneficial when convenience fee is <5%

Am I right?

My analogy with magnus is simple like on day 1 of month I see expenses for the month and if it’s above 70k I take magnus out for riding else its a sleeping cat and Amex cards will be used for offline pos and online sbi cb.
If scheduled 70k spends there then another 30k gets manufactured with some tricks and rotated haha

I am aware that there are ways to increase the points. But that is not my question.
Can you please let me know if my calculations are correct?
