30m to 60m DROP OFF

I’m sure you guys have heard of this one.

Today at the track I did 5 x 30m from blocks, and 3 x 60m from blocks w/ 8-10 min rest.

My times were: 3.99, 4.00, 4.01, 4.02, 4.00, 60m times 7.08, 7.10, 7.13.

All hand times by a VERY good timer.
I mean this o’l gal is off by .15 at meets compared to FAT.

From my 30m times I should have post at least 7.05 in the 60’s right?

I’m falling off for some reason after 30m.

I feel relaxed, but something is holding my times down.

I should be running 10.60 in the 100 m.

Have you guys experienced this?
