Since I believe the DC/MP Solids all come from the same lobe "family"........

First the advertised duration is incorrect (for what we're all used to)

The seat to seat duration is given @ .015" not .020"

To find duartion @ .020", subtract 8º from what MP tells you.

To find duration @ .050", subtract 32º(intensity)from the answer you got from above.

So, a 296º-.557" is really 288º @ .020"/256º @ .050"

312º-.590.........304º @ .020"/272º @ .050" and so on.
