In PLS-SEM, can AVE value and composite reliability be higher than 1.0?
I am using Smart PLS 3.0 program. And, in my study, three contructs have been made. Two constructs have only one indicator. And anothor one construct has three indicators. When we analyze PLS-SEM, AVE-value and composite reliability for the construct, which includes three indicators, are higher than 1.0. Is there any problem in the procedure of PLS-SEM? Usually, it is well-known that AVE values and composite reliabilities should be lower than 1.0.

Multicollinearity issues: is a value less than 10 acceptable for VIF?
Hello mates
Some papers argue that a VIF<10 is acceptable, but others says that the limit value is 5.
- "10" as the maximum level of VIF (Hair et al., 1995)
- "5" as the maximum level of VIF (Ringle et al., 2015)
Do you think there is any problem reporting VIF=6 ?
Maybe both limits are valid and that it depends on the researcher criteria...
Thank you in advance

Composite reliability more than 0.9 - desirable or undesirable?
In determining internal consistency reliability for measurement models, composite reliability values of more than 0.9 is deemed not desirable because this indicate "they are measuring the same phenomenon and are therefore unlikely to be a valid measure of the construct" (Hair et al., 2017)

However, discussions in forum have noted that values above 0.9 is acceptable, as it affirms unidimensionality of the construct, as long as items in the scale are not redundant http://forum.smartpls.com/viewtopic.php?f=5&t=3805 .
May I know is there any literature which explicitly addresses this issue ?
