Byakuya was barely able to dodge getsuga tenshou at shikai. Of course it's just a "big slow move", at bankai. And, quite frankly, I find the notion that Ichigo, who thought it'd be okay to challenge Byakuya to release his bankai and continue to fight at shikai, not being lucidly superior to Byakuya..also at shikai, whether it was thoughtless of him or not, entirely absurd. Nothing is shown to suggest that Byakuya could manage at shikai. There's not any..canon backing for it, at all. He calls getsuga tenshou slow, at..bankai. He barely dodged it at shikai. Nothing else is shown. As for what Byakuya said at bankai release: "I will not make you regret it. Before that, you will turn to dust and vanish from my sight." How does this in any way relate to shikai? Yeah. He won't make him regret it - at bankai. He will turn to dust and vanish from his sight, before he has the chance to regret it - at bankai. And regardless of whether or not Ichigo was superior to Byakuya at shikai, he insisted that Byakuya used bankai. He'd been insisting since before he used shikai. If he gets pawnt, his attitude towards it may have been met with some..regret, or looked upon as..regretable foolishness, regardless of whether it would eventually come to that, or not. And, in fact, unless Ichigo dies fighting Byakuya at shikai, it would inevitably come to that anyways, because if Ichigo has him pressured majorly at shikai, he'll use..bankai. Ichigo was able to see the individual blades coming at them, and strike them down at the last moment, to counter Byakuya's initial release with an attack of his own, that was narrowly evaded. Ichigo's attitude afterwards shows no doubt in his mind that shikai is not an issue in this sitaution. Nothing is really brought up in contradiction to this.

You've also missed the mark with bankai. "By focusing all of your bankai's power...into that small blade...you can fight at maximum force at super high speed." His bankai does not simply.."retain" the strength he had in his shikai state. Nothing is stated to suggest that, and the only difference between Ichigo's bankai, and other's, is that whereas bankai is normally a vast expansion, Ichigo's is a superdense compression - to assume that that would yet have no affect to augment power is rather farfetched, and rather baseless I'd say. The statement "fight at maximum force" hardly seems to indicate such a thing, as well. In addition, Ichigo has hardly mastered his bankai. He constantly lost speed, and his bones were cracking under the weight of his own spiritual pressure. Faced against Yammy, it is made not that Ichigo's reiatsu feels rather different than before, much more rough, and as Ulquiorra makes note, solid, impressed that he could gain such a mastery of bankai in such a short time - implying that this was note the case, when Ichigo had first made use of it. In fact, Hollow Ichigo taunted his counterpart, in his condition, exclaiming that he would show him how to use bankai, since Ichigo..apparantly couldn't handle it..and Ichigo has never really shown to have had those problems later. At that stage, he hardly had much master of bankai. As far as dodging Hollow Ichigo's kuroi getsuga tenshou thrice, all that happened in that exchange was that Byakuya took damage from a large sword wound down his shoulder and across the front of his body, slid backwards, called down a blade, only to be met with a kuroi getsuga tenshou coming straight at him, and in the next instant, another fired off from the side, and as he began to leap, Hollow Ichigo was already behind him, and he was struck by the attack, left heavily wounded and exhasperated. Dispite the advanced recovery in this state, Hollow Ichigo was furthermore making use of an injured body. And..plain old Ichigo is faster than Byakuya by a large margin, anyways, at bankai. Byakuya had completely lost sight of him twice, and upon finally catching him, had his attack repelled, as Ichigo swatted away all of the blades. Byakuya stated himself that Senkei does not increase his speed. Ichigo just got slower. It's anyone's guess if Hakuteiken has a speed benefit (personally, I find it likely, with all that reiatsu focused on his body).
