spinal column. Id. at 588. While this inspection, described by defense counsel as a “windshield appraisal,” id. at 640, was certainly not so complete an evaluation as possible, the District Court was within its discretion to say it provided a sufficient basis for Mr. Scott’s opinion to go to the jury. As the court told defendants’ counsel, “[y]ou can argue that to the jury, that he has absolutely no basis for that, that he pulled it out of the air.” Id. at 612. Jurors have enough sense to take such considerations into account during their deliberations.
On the issue of permanence of injury, the jury also had before it Ira Thurman’s testimony that prior to use of the Harvestore system, his herd produced a daily average of at least 40 pounds of milk a day per cow, id. at 229, and that the daily tank average at the time of trial was less than 28 pounds per cow, id. at 291. He also testified that a cow producing less than 28 pounds is worthless as a milk cow, and therefore the cattle were reduced from their worth as milk animals to their slaughter value, id. at 248. As far as the plaintiff’s use of the herd is concerned, this was permanent damage.12 In connection with this testimony, the jury also knew that Mr. Thurman kept virtually no written records of his own, on either the health or milk production of the individual cows, and that he could not say which animals actually were producing less than 28 pounds of milk a day. Id. at 291. But this, too, is a question of credibility. There was sufficient evidence for the jury to award damages based on the diminished value of the Circle J herd.
The state of Ira Thurman’s records, such as they are, is also connected to the defendants’ challenge to any award based on lost milk production, since plaintiff sought profits allegedly lost through damage to a revenue-producing asset as well as compensation for the fact that the asset itself became less valuable for purposes of sale. According to defendants, not only was Circle J’s milk loss a “hypothetical shortfall,” Appellant’s (AOSHPI) brief at 29, but plaintiff’s evidence went only to lost revenue, and failed to factor in the cost of performance, as required by Arkansas law. Robertson v. Ceola, 255 Ark. 703, 501 S.W.2d 764, 766 (1973). And defendants once again note that Mr. Thurman’s own actions could have contributed to any decrease in the herd’s production.
There is no question that Mr. Thurman’s evidence for lost milk production was homespun at best. He had records from the milk cooperative, and a production calendar kept by a farm hand, who received a bonus when the daily average went over 40 pounds per animal, as well as his tax records. As the District Court wisely noted, while even Mr. Thurman probably wishes his records were more complete, Tr. 231, the figures were adequately documented to raise a jury question. Prom that point, Mr. Thurman’s records and recall are a question of credibility.
Nor was the milk-production evidence incomplete for failure to factor in cost of performance. Robertson v. Ceola, cited by defendants, involved a cost-plus contract; plaintiff there failed to show what portion of the amount allotted for labor represented the value of his own services on the project. Here, there is no indication that the cost of performance would differ whether the herd was producing under 28 pounds per day or over 40 pounds.
IV.
Defendants claim that the District Court erred in submitting the deceit question to the jury, and that the District Court’s post-verdict grant of their motion for judgment n.o.v. did not cure the error,

Although he hesitated to call it permanent damage, Dr. Lawrence Price, a consultant for defendant A.O. Smith Harvestore Products, Inc., testified that rumen acidosis could mean a cow’s "milk production capability would be limited," and agreed with plaintiff’s counsel that this would be "[f]or the life of the cow.” Tr. 363.
