Can I go straight from the Altra Timp 4 to the Timp 6 and skip the Timp 5?

Yes, but going Timp 4 to Timp 6 means taking one change in a single step: the Timp 5 is where the ride moved. Drop holds at 0 mm, so the difference is foam and fit rather than geometry: Altra EGO MAX to Altra EGO MAX, updated formula.

How much did the weight change across these two updates?

0.5 oz off in total, 10.7 oz to 10.2 oz in a men's US 9. The Timp 5 took it to 9.5 oz first.

Is the Timp 5 the better buy than either of these?

On paper it splits them: 9.5 oz against 10.7 oz for the Timp 4 and 10.2 oz for the Timp 6, on a 29 mm heel and a $155 list price. Whether that is worth chasing depends on what the Timp 5 update actually did, which the section above works through.

Did the Timp get taller between the Timp 4 and the Timp 6?

Heel stack went 29 mm to 30 mm, by way of 29 mm on the Timp 5. Drop held at 0 mm throughout, so the extra foam sits under both ends.

Where does the Timp 6 sit in the Timp lineup now?

It is the current model, two versions on from the Timp 4 and the newest one you can buy at full retail.

THE SHORT ANSWER

Two updates and 3 years separate the Altra Timp 4 from the Timp 6. Net change: 0.5 oz lighter, 1 mm more heel stack, a new midsole, $5 more at list. The Timp 5 is where the character changed, and that is the update Timp 4 owners notice first.

Or buy the Timp 5 instead?

The Timp 5 is worth a look only if you want the ride it introduced, because that is the update that changed the shoe. Buying it to soften the jump does not work: you would be adapting to the same change either way, just at an older spec.
