Please Refer to CFAI text Vol 6

In Example 4 (P.130) & Example 5, the returns calculated by TWR & MWR are almost same. Furthermore, the footnote 19 at the bottom of P.286 stated that "MIRR" approximates a TWR. But the return (0.41%) calculated using True TWR and the return (0.51%) calculated using MIRR (MWRR?) are quite different.

Now there are 2 questions :
1. MIRR = MWRR ?
2. True TWR = TWR ? Why it is said "True" ?
