At this point its up to you to believe what you want (not saying your point don't make sense) but we cannot judge Gaara's sand speed by the manga because all the scans are stationary.
I've highlighted the important part. No, we can't judge, which means there is no real evidence for your claim. Mine has evidence, and that's the problem for you here.
Look, I agree, Gaara is fast, I've said so elsewhere. I think he'd solo the 3 non-Onoki Kage quite handily. That said, it's a long, long way from being able to argue Deidara is close to fast enough to react to Tsunade. Even Gaara's big sand speed feats of blocking A's foot, and catching the 3rd Raikage, aren't great arguments, because neither was necessarily going at anything like full speed when that happened. Likewise, let's assume Gaara
is faster than the Raikage (he isn't at full speed, though with all the sand defences he has by the time Raikage powers up it won't matter). So what? We don't know any of the important info that would allow that to translate to help Deidara:
- was Gaara's sand moving at full speed or close to it?
- how far away was the sand when it went for Deidara?
- Deidara already had an escape vehicle waiting for him to jump on to get away
Right after Deidara "gets away" he gets his hand crushed by Gaara (while mounted, which helps his speed greatly)... so much for his great reaction speed. And he even tells us, he got caught because Gaara was using his "faster" sand (from his gourd), so before Gaara assumedly was using slower normal sand. None of this helps Deidara's cause.

Yes, Tsunade is slower than A... full speed A... but again, that doesn't lead to the conclusion that Deidara is fast, because of the above problems.
What i think your neglecting in this case is Air resistance in tsunade's jumps and the fact that Tsunade isn't A so as all the force she initially moved with is converted to energy, she slows down (basic physics) In the caso of A however, A's Raiton no Yoroi will greatly increase his speed, power and reaction time giving him the ability to counter air resistance being that his speed only increases the longer he travel's.
Given the 30 meters lets convert it to feet. 30 meters = 98.425 feet. Are you trying to tell me that deidara wouldn't notice un-maneuverable tsunade coming at high speeds from 98 feet away? even given the fact that she's slower than raikage?
Huh? Firstly, the fight specified 30 feet between them, not 30 m's. Secondly, I don't see how your physics above helps. Tsunade is slowed down in her jump... she won't be when she jumps horizontally (not vertically) right at Deidara's pointy blonde head (unrestrained by hundreds and hundreds of tonnes of weight). I don't understand your argument. If Tsunade wanted to jump 100 feet forward, how long do you think it would take her to reach her target?
We've already seen that a Stright forward attact by A was dodged by Naruto because of A's complete linear movement.
No, Naruto dodged it because he was in Sage mode, and that let him sense his attack coming early and respond to it (Jedi style). Deidara doesn't have that, so he can't do it.
As for the Databook, you won't have to look at my post history for long to get an idea of what I think about it. It's trash, and should never be the basis of a serious argument. It's also full of horrible inconsistencies, my favourite being Itachi and Oro both getting the same rating for Genjutsu. Seriously, don't care what the databook says (and even if I did, for all we know his "speed" is factoring in his speed while mounted, which is definitely good, unlike his normal speed, which is definitely crap).
