and they all assume that your last day of work is in 2019?
If so, then those pension benefits look attractive compared to taking a $85k lump sum now and investing in a deferred annuity.

But that doesn't necessarily make leaving it best if you are willing to take some risk. If you took the payout and invested it in a balanced mutual fund and left it alone and earned only 5%, which is more likely than not, in 10, 15 and 20 years you would have $155k, $197k or $252k.... and based on current annuity payout rates for life annuities at those ages your monthly benefit would be $730, $1,011 or $1,436.
I just picked 5% off the top of my head but interestingly that growth comes out the same as the growth in your pension at current annuity rates. However, you could do better or worse than 5% in a balanced mutual fund... or annuity rates could change... that is where the risk comes in.
But I'm guessing that the payouts that you quoted might not be guaranteed but just projected. I know that I retired I left my DC pension balance with my employer because at the time the annuity rates that they offered were better than the immediate annuities market... however a few years later they had updated their annuity rates so taking a pension benefit was no longer attractive so I ended up taking the lump sum.
