Salaries on paysa.com look right to you?
For e.g. check this one out. 170K base (average) for a TPM at McAfee. https://www.paysa.com/salaries/mcafee--technical-project-manager Is it fair to say they are averaging salaries from a wide range of experience levels? Still 155K for lower end seems high to me.
